Purposes The aim of this study was to analyse how well FRAX® predicts the risk of major osteoporotic and vertebral fractures over 6 years in postmenopausal women from general population. Patients and methods The OPUS study was conducted in European women aged above 55 years, recruited in 5 centers from random population samples and followed over 6 years. The population for this study consisted of 1748 women (mean age 74.2 years) with information on incident fractures. 742 (43.1%) had a prevalent fracture; 769 (44%) and 155 (8.9%) of them received an antiosteoporotic treatment before and during the study respectively. We compared FRAX® performance with and without bone mineral density (BMD) using receiver operator characteristic (ROC) c-statistical analysis with ORs and areas under receiver operating characteristics curves (AUCs) and net reclassification improvement (NRI). Results 85 (4.9%) patients had incident major fractures over 6 years. FRAX® with and without BMD predicted these fractures with an AUC of 0.66 and 0.62 respectively. The AUC were 0.60, 0.66, 0.69 for history of low trauma fracture alone, age and femoral neck (FN) BMD and combination of the 3 clinical risk factors, respectively. FRAX® with and without BMD predicted incident radiographic vertebral fracture (n = 65) with an AUC of 0.67 and 0.65 respectively. NRI analysis showed a significant improvement in risk assignment when BMD is added to FRAX®. Conclusions This study shows that FRAX® with BMD and to a lesser extent also without FN BMD predict major osteoporotic and vertebral fractures in the general population. PMID:24386199

Atmospheric remote sensing by instruments such as spectrometers and interferometers often requires scheduling that is dependent on external factors, for example; time and solar (or lunar) zenith angle. Such instruments manufactured by Bruker often use the software package OPUS, which, while useful, is not flexible enough for automatic, repeated, atmospheric measurements of this nature. In this brief paper, we describe ASAP, a Python tool developed to run our network of Fourier transform interferometers in New Zealand and Antarctica. It allows the automated scheduling of measurements by time, lunar, or solar zenith angle while accounting for weather or other external parameters. There is a wide range of useful functions, all packaged in a simple graphical user interface; it is available on request.

As a consequence of a rapid growth of an ageing population, more people with dementia are expected on the roads. Little is known about whether these people are at increased risk of road traffic-related accidents. Our study aims to investigate the risk of road traffic-related accidents for people aged 65 years or older with a diagnosis of dementia in Denmark. We will conduct a nationwide population-based cohort study consisting of Danish people aged 65 or older living in Denmark as of January 1, 2008. The cohort is followed for 7 years (2008-2014). Individual's personal data are available in Danish registers and can be linked using a unique personal identification number. A person is identified with dementia if the person meets at least one of the following criteria: (1) a diagnosis of the disease in the Danish National Patient Register or in the Danish Psychiatric Central Research Register, and/or (2) at least one dementia diagnosis-related drug prescription registration in the Danish National Prescription Registry. Police-, hospital-, and emergency room-reported road traffic-related accidents occurred within the study follow-up are defined as the study outcome. Cox proportional hazard regression models are used for the main analysis. Our study protocol has 3 phases including data collection, data analysis, and reporting. The first phase of register-based data collection of 853,228 individual's personal information was completed in August, 2016. The next phase is data analysis, which is expected to be finished before December 2016, and thereafter writing publications based on the findings. The study started in January 2016 and will end in December 2018. This study covers the entire elderly population of Denmark, and thereby will avoid selection bias due to nonparticipation and loss to follow-up. Furthermore, this ensures that the study results are reliable and generalizable. However, underreporting of traffic-related accidents may occur, which will limit estimation

Studies confirm that calcium inhibits iron absorption. Danish tap water comes from groundwater, which contains varying amounts of calcium depending on the subsoil. We investigated the association of calcium in drinking water with iron levels in Danish blood donors. We used data on Danish blood donors including dietary and lifestyle habits, blood donation history, and physiologic characteristics including measures of ferritin levels along with information on area of residence from The Danish Blood Donor Study. Data on calcium levels in groundwater ("water hardness") were obtained through the Geological Survey of Denmark and Greenland. We performed multiple linear and logistic regression analyses to evaluate the effect of water hardness on ferritin levels and risk of having iron deficiency (defined as ferritin levels <15 ng/mL), stratified by sex. There was a significant negative association between water hardness and ferritin levels in both men and women. Risk of iron deficiency was correspondingly increased in both men (odds ratio [OR], 1.55; 95% confidence interval [CI], 1.14-2.12) and women (OR, 1.20; 95% CI, 1.03-1.40) with increasing water hardness. In analyses restricted to individuals who received supplemental iron tablets no significant association between groundwater hardness and ferritin levels was observed. As measured by ferritin levels, residential drinking water calcium content is associated with blood donors- iron levels and risk of iron deficiency. However, effect sizes are small. © 2018 AABB.

Prolonged sitting has been negatively associated with a range of non-communicably diseases. However, the role of occupational sitting is less clear, and little is known on the changes of occupational sitting in a working population over time. The present study aimed to determine 1) temporal changes in occupational sitting time between 1990 and 2010 in the Danish workforce; 2) the association and possible dose-response relationship between occupational sitting time and all-cause mortality. This study analysed data from the Danish Work Environment Cohort Study (DWECS), which is a cohort study of the Danish working population conducted in five yearly intervals between 1990 and 2010. Occupational sitting time is self-reported in the DWECS. To determine the association with all-cause mortality, the DWECS was linked to the Danish Register of Causes of Death via the Central Person Register. Between 1990 and 2010 the proportion of the Danish workforce who sat for at least three quarters of their work time gradually increased from 33.1 to 39.1%. All-cause mortality analyses were performed with 149,773 person-years of observation and an average follow-up of 12.61 years, during which 533 deaths were registered. None of the presented analyses found a statistically significant association between occupational sitting time and all-cause mortality. The hazard ratio for all-cause mortality was 0.97 (95% CI: 0.79; 1.18) when ≥24 hr/wk occupational sitting time was compared to <24 hr/wk for the 1990-2005 waves. Occupational sitting time increased by 18% in the Danish workforce, which seemed to be limited to people with high socio-economic status. If this increase is accompanied by increases in total sitting time, this development has serious public health implications, given the detrimental associations between total sitting time and mortality. The current study was inconclusive on the specific role that occupational sitting might play in the increased all-cause mortality risk

Gender stereotyping in television advertisements: a study of French and Danish television.

Two similar, but not identical, content analyses of the portrayals of men and women in French and Danish television advertisements are reported. By partially replicating and extending past investigations conducted in America, Australia, Britain, Hong Kong, Indonesia, Italy, Kenya, and New Zealand, it was predicted that there would be more gender stereotyping in French television advertisements and less gender stereotyping in Danish television advertisements. In the first study, 165 French television advertisements were analyzed by following established coding categories (A. Furnham & E. Skae, 1997; L. Z. McArthur & B. G. Resko, 1975). Contrary to prediction, the results showed that traditional gender role portrayal on French television was no different from that found in other countries. Separate statistical analyses were carried out for visually versus aurally classified central figures, yet this yielded relatively few significant differences. In the second study, a sample of 151 Danish advertisements was analyzed; results showed that Danish television was generally less gender stereotypic than French television in its portrayal of women. Exactly half (5) of the coding categories showed significant differences. Finally, an international statistical comparison between these two studies and similar research in Australia, Britain, and Italy was carried out. The methodological implications of these results are discussed as well as the theoretical issues arising from other studies of this sort.

To compare the effects of five years of specialised early intervention (SEI) treatment for first episode schizophrenia spectrum disorder with the standard two years of SEI plus three years of treatment as usual. Randomised, superiority, parallel group trial with blinded outcome assessment. Randomisation was centralised and computerised with concealed randomisation sequence carried out at an external site. Participants were recruited from six OPUS teams in Denmark between 2009 and 2012. OPUS teams provide SEI treatment to all patients diagnosed with a schizophrenia spectrum disorder in Denmark. 400 participants (51% women) with a mean age of 25.6 (standard deviation 4.3) were randomised to five years of SEI (experimental intervention; n=197) or to two years of SEI plus three years of treatment as usual (control; n=203). OPUS treatment consists of three core elements-modified assertive community treatment, family involvement, and social skill training-with a patient-case manager ratio of no more than 12:1. For participants randomised to five years of OPUS treatment, the treatment was largely unchanged. Participants randomised to the control group were mostly referred to community health centres after two years of SEI treatment. Follow-up assessments were conducted five years after start of OPUS treatment. Primary outcome was negative symptoms measured on the scale for assessment of negative symptoms (avolition-apathy, anhedonia, alogia, and affective blunting). Secondary outcomes were remission of both negative and psychotic symptoms, psychotic symptoms, suicidal ideation, substance abuse, compliance with medical treatment, adherence with treatment, client satisfaction, days in hospital care, and labour market affiliation. Levels of negative symptoms did not differ between the intervention group and control group (1.72 v 1.81 points; estimated mean difference -0.10 (95% confidence interval -0.33 to 0.13), P=0.39).

Aims: Seafarers aboard oil and chemical tankers may be exposed to many chemicals, including substances like benzene that are known to be carcinogenic. Other seafarers are exposed to engine exhaust, different oil products, and chemicals used aboard and some years ago asbestos was also used extensively in ships. The aim of this study was to study cancer morbidity among Danish seafarers in relation to type of ship and job title. Methods: A cohort of all Danish seafarers during 1986–1999 (33 340 men; 11 291 women) registered by the Danish Maritime Authority with an employment history was linked with the nationwide Danish Cancer Registry and followed up for cancer until the end of 2002. The number of person years at risk was 517 518. Standardised incidence ratios (SIR) were estimated by use of the corresponding national rates. Results: The SIR of all cancers combined was higher than expected: 1.26 (95% CI 1.19 to 1.32) for men and 1.07 (95% CI 0.95 to 1.20) for women. This was mainly due to an excess of cancer of the larynx, lung, tongue, mouth, pharynx, oesophagus, pancreas, kidney, urinary bladder, colon, and bone as well as skin melanomas among men (the three latter borderline significantly increased), and an excess of cancer of the lung, rectum, and cervix uteri among women. The differences in risk pattern for lung cancer between the different job categories among men ranged in terms of SIR from 1.2 (95% CI 0.9 to 1.7) (engine officers) to 2.3 (1.6 to 3.3) (engine room crew), and 4.1 (2.1 to 7.4) among maintenance crew. Non-officers had a 1.5 times higher lung cancer risk than officers. No increased occurrence of all lymphatic and haematopoietic malignancies combined was found for employees on tankers, but the number of cases was limited to a total of 7. Conclusions: Danish seafarers, especially men, face an increased overall cancer risk, in particular a risk for lung cancer and other tobacco associated cancers. PMID:16234401

Fe and n-3 long-chain PUFA (n-3 LCPUFA) have both been associated with cognition, but evidence remains inconclusive in well-nourished school-aged children. In the Optimal Well-Being, Development and Health for Danish Children through a Healthy New Nordic Diet (OPUS) School Meal Study, the 3-month intervention increased reading performance, inattention, impulsivity and dietary intake of fish and Fe. This study investigated whether the intervention influenced n-3 LCPUFA and Fe status and, if so, explored how these changes correlated with the changes in cognitive performance. The study was a cluster-randomised cross-over trial comparing school meals with packed lunch (control). At baseline and after each treatment, we measured serum ferritin, whole-blood n-3 LCPUFA and Hb, and performance in reading, mathematics and d2-test of attention. Data were analysed using mixed models (n 726) and principal component analysis of test performances (n 644), which showed two main patterns: 'school performance' and 'reading comprehension'. The latter indicated that children with good reading comprehension were also more inattentive and impulsive (i.e. higher d2-test error%). The intervention improved 'school performance' (P=0·015), 'reading comprehension' (P=0·043) and EPA+DHA status 0·21 (95% CI 0·15, 0·27) w/w % (P<0·001), but it did not affect serum ferritin or Hb. At baseline, having small Fe stores was associated with poorer 'school performance' in girls, but with better 'reading comprehension' in both boys and girls. Both baseline EPA+DHA status and the intervention-induced increase in EPA+DHA status was positively associated with 'school performance', suggesting that n-3 LCPUFA could potentially explain approximately 20 % of the intervention effect. These exploratory associations indicate that increased fish intake might explain some of the increase in reading performance and inattention in the study.

The nationwide Danish Cancer Registry and the Danish Melanoma Database both record data on melanoma for purposes of monitoring, quality assurance, and research. However, the data quality of the Cancer Registry and the Melanoma Database has not been formally evaluated. We estimated the positive predictive value (PPV) of melanoma diagnosis for random samples of 200 patients from the Cancer Registry (n = 200) and the Melanoma Database (n = 200) during 2004-2014, using the Danish Pathology Registry as "gold standard" reference. We further validated tumor characteristics in the Cancer Registry and the Melanoma Database. Additionally, we estimated the PPV of in situ melanoma diagnoses in the Melanoma Database, and the sensitivity of melanoma diagnoses in 2004-2014. The PPVs of melanoma in the Cancer Registry and the Melanoma Database were 97% (95% CI = 94, 99) and 100%. The sensitivity was 90% in the Cancer Registry and 77% in the Melanoma Database. The PPV of in situ melanomas in the Melanoma Database was 97% and the sensitivity was 56%. In the Melanoma Database, we observed PPVs of ulceration of 75% and Breslow thickness of 96%. The PPV of histologic subtypes varied between 87% and 100% in the Cancer Registry and 93% and 100% in the Melanoma Database. The PPVs for anatomical localization were 83%-95% in the Cancer Registry and 93%-100% in the Melanoma Database. The data quality in both the Cancer Registry and the Melanoma Database is high, supporting their use in epidemiologic studies.

Diet is recognised as one modifiable lifestyle factor for ischaemic heart disease (IHD). We aimed at investigating the associations between adherence to the Danish Food-Based Dietary Guidelines (FBDG) indicated by a Dietary Quality Index (DQI) and selected cardiometabolic risk factors in a cross-sectional study with 219 Danish adult participants (59 %women; age 31-65years) with a minimum of one self-rated risk marker of IHD. Information regarding diet was obtained using web-based dietary assessment software and adherence to the Danish FBDG was expressed by a DQI calculated from 5 food and nutrient indicators (whole grain, fish, fruit and vegetables, energy from saturated fat and from added sugar). Background information, blood samples and anthropometrics were collected and blood pressure was measured. Linear regression analyses were used to evaluate the association between DQI and cardiometabolic risk factors. DQI was inversely associated with LDL:HDL ratio and TAG (-0·089 per unit; 95 % CI -0·177, -0·002 and -5 % per unit; 95 % CI -9, 0, respectively) and positively associated with HDL-cholesterol (0·047 mmol/l per unit; 95 % CI 0·007, 0·088). For men, DQI was inversely associated with BMI (-3 %per unit; 95 % CI -5, -1), trunk fat (-1 % per unit; 95 % CI -2, -1), high-sensitivity C-reactive protein (-30 % per unit; 95 % CI -41, -16 %), HbA1c (-0·09 % per unit; 95 % CI -0·14, -0·04), insulin (-13 % per unit; 95 % CI -19, -7) and homoeostatic model assessment-insulin resistance (-14 % per unit; 95 % CI -21, -7). In women, DQI was positively associated with systolic blood pressure (2·6 mmHg per unit; 95 % CI 0·6, 4·6). In conclusion, higher adherence to the current Danish FBDG was associated with a more beneficial cardiometabolic risk profile in a Danish adult population with a minimum of one self-rated risk factor for IHD.

Dynamic Heights in the Great Lakes using OPUS Projects

The U.S. will be implementing new geometric and vertical reference frames in 2022 to replace the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88), respectively. Less emphasized is the fact that a new dynamic height datum will also be defined about the same time to replace the International Great Lakes Datum of 1985 (IGLD 85). IGLD 85 was defined concurrent with NAVD 88 and used the same geopotential values. This paper focuses on the use of an existing tool for determining geometric coordinates and a developing geopotential model as a means of determining dynamic heights. The Online Positioning User Service (OPUS) Projects (OP) is an online tool available from the National Geodetic Survey (NGS) for use in developing geometric coordinates from simultaneous observations at multiple sites during multiple occupations. With observations performed at the water level gauges throughout the Great Lakes, the geometric coordinates of the mean water level surface can be determined. NGS has also developed the xGEOID15B model from satellite, airborne and surface gravity data. Using the input geometric coordinates determined through OP, the geopotential values for the water surface at the water level stations around the Great Lakes were determined using the xGEOID15B model. Comparisons were made between water level sites for each Lake as well as to existing IGLD 85 heights. A principal advantage to this approach is the ability to generate new water level control stations using OP, while maintaining the consistency between orthometric and dynamic heights by using the same gravity field model. Such a process may provide a means for determining dynamic heights for a future Great Lakes Datum.

Limited knowledge of the influence of lifestyle risk factors and religious living on chronic neurological diseases exists. Seventh-day Adventists (SDA) do not consume tobacco, alcohol, or pork, and many adhere to lacto-ovo-vegetarian diet, and Baptists discourage excessive use of alcohol and tobacco. We investigated whether the incidence of four common chronic neurological illnesses: dementia, Alzheimer's disease, Parkinson's disease, and epilepsy in a large cohort of Danish Adventists and Baptists was different compared to the general Danish population. Three of the illnesses are neurodegenerative, whereas epilepsy can occur at any age. We compared hospital admission rates for some major neurological diseases among members of the Danish Religious Societies Health Study comprising 6,532 SDA and 3,720 Baptists with the general Danish population. Standardized incidence ratios (SIR) stratified by sex, age, and calendar time were calculated. SIR of dementia or Alzheimer's disease was significantly decreased for members of both communities (SDA, 0.78; 95% CI, 0.67-#x2013;0.90 and Baptists, 0.59; 0.47-#x2013;0.73). The SIRs of Parkinson's disease and epilepsy were not significantly different compared to the general population. We observe reduced incidence for dementia or Alzheimer's disease in a large cohort of members of two religious communities characterized by lifestyle recommendations. More studies are needed to disentangle the interaction between such lifestyle and other components of the religious belief system.

In Denmark it is permitted to draw overhead lines across residential areas. In connection with a Danish case-control study we developed a method for estimating the historical values of magnetic fields at residences. The study included 1,707 cases with childhood cancer and 4,788 matched population controls. A total of 16,082 different addresses had been occupied by the families from the time of conception until the date of diagnosis. The values of the extreme, maximum, middle and minimum 50 Hz magnetic field strengths originating from a 50-400 kV high-voltage installation were estimated for each of the dwellings included in a potential exposure area. 30 children were exposed to an average level of magnetic fields of 0.1 microT or more. The evaluated Danish method of exposure assessment was compared with the method for residential wiring codes developed by Wertheimer and Leeper /1/. We concluded that the US wiring codes are inappropriate for use in connection with the Danish electricity transmission system.

To determine the prevalence of amblyopia in Denmark before and after the initiation of the Danish national preschool vision screening programme. In a population-based cross-sectional study, 3826 participants of the Danish General Suburban Population Study (GESUS) aged 20 years and older from a Danish rural municipality received a complete general health examination and an ophthalmological interview and examination. This study included a comprehensive ophthalmologic interview, measurement of best corrected visual acuity (BCVA) in each eye, Hirschberg's test for strabismus and two 45-degree retinal fundus photographs of each eye. A complete ophthalmologic examination was performed when indicated. The prevalence of monocular visual impairment (MVI) was 4.26% (95% CI, 3.66-4.95, n = 163). Amblyopia was the most common cause, accounting for 33%. The prevalence of amblyopia was 1.44% (95% CI, 1.01-1.81, n = 55), being higher among non-preschool vision screened persons compared to those who were offered (estimated 95% attendance) preschool vision screening (1.78%, n = 41, 95% CI 1.24-2.33 versus 0.44%, n = 2, 95% CI, 0.12-1.60, p = 0.024). The leading cause of amblyopia was anisometropia (45.5%, 25/55). Amblyopia was the most common cause of MVI. Following the initiation of the Danish national preschool vision screening programme, which has an approximate attendance rate of 95%, the prevalence of amblyopia decreased by fourfold. © 2014 Acta Ophthalmologica Scandinavica Foundation.

Recent legislation in Denmark has made it possible for dentists to delegate their tasks to dental hygienists. Previous studies have shown that Danish dental hygienists primarily were performing assignments within their own work field. These assignments include prophylaxis or instructing patients in oral health care. However, studies have also shown that Danish dental hygienists performed dental nurse assignments such as chair-side assistance, unit cleaning and disinfection of instruments. The objectives of this study were to investigate (i) the range of work assignments performed by Danish dental hygienists, (ii) the types of dentist tasks performed by Danish dental hygienists and (iii) job satisfaction among Danish dental hygienists. Dental hygienists graduating in 2004-2007 were invited to participate in this study. Participants answered an email-distributed questionnaire. The questionnaire consisted of questions regarding job satisfaction, assignments performed, postgraduate course attendance, receiving assistance from a dental nurse and which work assignments Danish dental hygienists wish to perform in the future. The results of this study showed that 90% of Danish dental hygienists were satisfied with their job and 52% were performing dentists' tasks. Among dentists' tasks performed by Danish dental hygienists, invasive caries therapy was the most frequently performed task. The type of assignments performed by Danish dental hygienists today appears to be changing compared to previous studies. From initially performing prophylaxis and chair-side assistance for the dentist, Danish dental hygienists today are performing a wider range of tasks which includes dentists' tasks. © 2016 John Wiley & Sons A/S.

The Danish Blood Donor Study (DBDS) is a prospective, population-based study and biobank. Since 2010, 100,000 Danish blood donors have been included in the study. Prior to July 2015 all participating donors had to complete a paper-based questionnaire. Here we describe the establishment of a digital tablet-based questionnaire platform implemented in blood bank sites across Denmark. The digital questionnaire was developed using the open source survey software tool LimeSurvey. The participants accesses the questionnaire online with a standard SSL encrypted HTTP connection using their personal civil registration numbers. The questionnaire is placed at a front-end web server and a collection server retrieves the completed questionnaires. Data from blood samples, register data, genetic data and verification of signed informed consent are then transferred to and merged with the questionnaire data in the DBDS database. The digital platform enables personalized questionnaires, presenting only questions relevant to the specific donor by hiding unneeded follow-up questions on screening question results. New versions of questionnaires are immediately available at all blood collection facilities when new projects are initiated. The digital platform is a faster, cost-effective and more flexible solution to collect valid data from participating donors compared to paper-based questionnaires. The overall system can be used around the world by the use of Internet connection, but the level of security depends on the sensitivity of the data to be collected. Copyright © 2016 The Authors.

Growing consumer awareness of functional foods and understanding of their positive nutritional effects have led to the need of specific studies and have captured more attention than ever before. In Europe, Danish consumers have been found to be relatively negative towards the concept of functional foods. This paper presents the results of a qualitative pilot study that aimed to explore Danish consumers' motives for choosing omega-3/fish oil enriched products. The Health Action Process Approach (HAPA) was applied as a theoretical framework to understand the process by which people choose healthy foods. By conducting qualitative in-depth interviews the study mostly focused on the role of behavioural intention predictors such as risk perception, outcome expectations and self-efficacy. The results of the study suggest that consumers' understanding of healthy eating as such does not relate to the choice of omega-3/fish oil, whereas perception of omega-3 as an ingredient in selected foods does indeed influence consumers' choice of carrier-ingredient combinations.

A direct way to evaluate food-based dietary guidelines is to assess if adherence is associated with development of non-communicable diseases. Thus, the objective was to develop an index to assess adherence to the 2013 Danish food-based dietary guidelines and to investigate the association between adherence to the index and risk of myocardial infarction (MI). Population-based cohort study with recruitment of participants in 1993-1997. Information on dietary intake was collected at baseline using an FFQ and an index ranging from 0 to 6 points was created to assess adherence to the 2013 Danish food-based dietary guidelines. MI cases were identified by record linkage to the Danish National Patient Register and the Causes of Death Register. Cox proportional hazards models were used to estimate hazard ratios (HR) of MI. Greater areas of Aarhus and Copenhagen, Denmark. Men and women aged 50-64 years (n 55 021) from the Diet, Cancer and Health study. A total of 3046 participants were diagnosed with first-time MI during a median follow-up of 16·9 years. A higher Danish Dietary Guidelines Index score was associated with a lower risk of MI. After adjustment for potential confounders, the hazard of MI was 13 % lower among men with a score of 3-<4 (HR=0·87; 95 % CI 0·78, 0·96) compared with men with a score of <3. The corresponding HR among women was 0·76 (95 % CI 0·63, 0·93). Adherence to the 2013 Danish food-based dietary guidelines was inversely associated with risk of MI.

Background Prior studies have suggested that military service may be associated with the development of amyotrophic lateral sclerosis. We conducted a population-based case-control study in Denmark to assess whether occupation in the Danish military is associated with an increased risk of developing amyotrophic lateral sclerosis. Methods There were 3,650 incident cases of amyotrophic lateral sclerosis recorded in the Danish National Patient Registry between 1982 and 2009. Each case was matched to 100 age- and sex-matched population controls alive and free of amyotrophic lateral sclerosis on the date of the case diagnosis. Comprehensive occupational history was obtained from the Danish Pension Fund database, which began in 1964. Results 2.4% (n=8,922) of controls had a history of employment in the military prior to the index date. Military employees overall had an elevated rate of ALS (OR=1.3; 95% CI: 1.1-1.6). A ten-year increase in years employed by the military was associated with an odds ratio of 1.2 (95% CI: 1.0-1.4), and all quartiles of time employed were elevated. There was little suggestion of a pattern across calendar year of first employment, but there was some evidence that increasing age at first employment was associated with increased ALS rates. Rates were highest in the decade immediately following the end of employment (OR=1.6; 95% CI: 1.2-2.2). Conclusions In this large population-based case-control study, employment by the military is associated with increased rates of ALS. These findings are consistent with earlier findings that military service or employment may entail exposure to risk factors for ALS. PMID:26583610

  The present study describes the development and formative evaluation of the Web-based Dietary Assessment Software for Children (WebDASC). WebDASC is part of the OPUS project ('Optimal well-being, development and health for Danish children through a healthy New Nordic Diet') and was intended to measure dietary change resulting from a school-based intervention.   WebDASC was developed as a self-administered tool that could be used by 8-11-year-old children with or without parent's aid. The development of WebDASC followed a prototyping approach: focus groups, informal interviews, literature review, and usability tests preceded its release. Special consideration was given to age-appropriate design issues.   In WebDASC an animated armadillo guides respondents through six daily eating occasions and helps them report foods and beverages previously consumed. A database of 1300 food items is available either through category browse or free text search, aided by a spell check application. A type-in format is available for foods not otherwise found through category browse or text search. Amount consumed is estimated by selecting the closest portion size among four different digital images. WebDASC includes internal checks for frequently forgotten foods, and the following features to create motivation: a food-meter displaying cumulative weight of foods reported, a most popular food ranking, and a computer game with a high score list.   WebDASC was developed as an intuitive, cost-effective, and engaging method to collect detailed dietary data from 8- to 11-year-old children. Preliminary testing demonstrated that it was well accepted among children. © 2012 The Authors. Journal of Human Nutrition and Dietetics © 2012 The British Dietetic Association Ltd.

A breast cancer diagnosis affects an individual's affiliation to labour market, but the long-term consequences of breast cancer on income in a Danish setting have not been examined. The present study investigated whether breast cancer affected future income among Danish women that participated in the work force. We also examined the roles of sociodemographic factors and prior psychiatric medical treatment. This registry-based cohort study was based on information retrieved from linked Danish nationwide registries. We compared the incomes of 13,101 women (aged 30-59 years) diagnosed with breast cancer (exposed) to those of 60,819 women without breast cancer (unexposed). Changes in income were examined during a 10-year follow-up; for each follow-up year, we calculated the mean annual income and the relative change compared to the income earned one year prior to diagnosis. Expected changes in Danish female income, according to calendar year and age, were estimated based on information from Statistics Denmark. For exposed and unexposed groups, the observed income changes were dichotomized to those above and those below the expected change in income in the Danish female population. We examined the impact of breast cancer on income each year of follow-up with logistic regression models. Analyses were stratified according to educational level, marital status, and prior psychiatric medical treatment. Breast cancer had a temporary negative effect on income. The effect was largest during the first three years after diagnosis; thereafter, the gap narrowed between exposed and unexposed cohorts. The odds ratio for an increase in income in the cancer cohort compared to the cancer-free cohort was 0.81 (95% CI 0.77-0.84) after three years. After seven years, no significant difference was observed between cohorts. Stratified analyses demonstrated that the negative effect of breast cancer on income lasted longest among women with high educational levels. Being single or having

To assess the association between polycystic ovary syndrome (PCOS) and cancer, especially of the endometrium, breast and ovary. The Danish National Patient Register was used to identify 12,070 in- and outpatients in whom PCOS was diagnosed when they were aged 9-49 years during 1977-2012. Using the Danish Cancer Registry, we followed the cohort through 2012 and compared the women's cancer incidence with that of the general Danish female population by means of standardized incidence ratios (SIRs). Cancer was diagnosed in 279 women with PCOS (SIR = 1.19; 95% CI = 1.06-1.34). We found an almost fourfold increased risk for endometrial cancer (numbers observed (N) = 16, SIR = 3.9; 95% CI = 2.2-6.3), the large majority of cases being type 1 (N = 14, SIR = 4.7; 95% CI = 2.6-7.9). We found no association between PCOS and breast (N = 59, SIR = 1.1; 95% CI = 0.8-1.4) or ovarian cancer (N = 10, SIR = 1.8; 95% CI = 0.8-3.2); however, significantly increased risks were found for kidney, colon and brain cancers. The results of this large cohort study support those of case-control studies showing that women with PCOS are at increased risk for endometrial cancer, whereas their risks for breast and ovarian cancer are similar to those of women in the general population. Our finding that women with PCOS also are at increased risk for cancers of the kidney, colon and brain requires further study. Copyright © 2014 Elsevier Inc. All rights reserved.

Objectives To describe experiences with the implementation of global trigger tool (GTT) reviews in five Danish hospitals and to suggest ways to improve the performance of GTT review teams. Design Retrospective observational study. Setting The measurement and monitoring of harms are crucial to campaigns to improve the safety of patients. Increasingly, teams use the GTT to review patient records and measure harms in English and non-English-speaking countries. Meanwhile, it is not clear as to how the method performs in such diverse settings. Participants Review teams from five Danish pilot hospitals of the national Danish Safer Hospital Programme. Primary and secondary outcome measures We collected harm rates, background and anecdotal information and reported patient safety incidents (PSIs) from five pilot hospitals currently participating in the Danish Safer Hospital Programme. Experienced reviewers categorised harms by type. We plotted harm rates as run-charts and applied rules for the detection of patterns of non-random variation. Results The hospitals differed in size but had similar patient populations and activity. PSIs varied between 3 and 12 per 1000 patient-days. The average harm rate for all hospitals was 60 per 1000 patient-days ranging from 34 to 84. The percentage of harmed patients was 25 and ranged from 18 to 33. Overall, 96% of harms were temporary. Infections, pressure ulcers procedure-related and gastrointestinal problems were common. Teams reported differences in training and review procedures such as the role of the secondary reviewer. Conclusions We found substantial variation in harm rates. Differences in training, review procedures and documentation in patient records probably contributed to these variations. Training reviewers as teams, specifying the roles of the different reviewers, training records and a database for findings of reviews may improve the application of the GTT. PMID:23065451

Occupational exposure of firefighters involves a complex range of potential health threats from toxic chemicals, shift work, extreme heat, physical and emotional strain. The aim of this study is to examine overall and disease-specific mortality among Danish firefighters. Through systematic collection of personnel and membership records from employers and trade unions, past and present male Danish firefighters were identified (n = 11,775). Using the unique Danish personal identification number, information on additional employment, vital status and cause of death was linked to each member of the cohort from the Supplementary Pension Fund Register, the Danish Civil Registration System and the Danish Register of Causes of Death. Standardized mortality ratios (SMRs) were calculated for specific causes of death using rates for two reference groups, a random sample of the male working population (n = 262,168) and the military (n = 396,739), respectively. Overall mortality was significantly reduced among the firefighters compared to both the sample of the working population and the military (SMR 0.74, 95% CI 0.69-0.78 and SMR 0.88, 95% CI 0.83-0.93). Further, the SMRs for endocrine diseases, mental disorders, non-traffic related accidents and other external causes were significantly lower against both reference groups. Death from stomach cancer was significantly increased among the full time firefighters, while part time/volunteer workers shared a significant increase in prostate cancer death compared to both references. Despite potential exposure to several occupational hazards, male Danish firefighters have a lower mortality than both the Danish working population in general and Danish military employees.

Background: Dietary and endogenously formed long-chain polyunsaturated fatty acids (LCPUFAs) are hypothesized to improve cognitive development, but results are inconclusive, with suggestions of sex specificity. One study suggested that single-nucleotide polymorphisms (SNPs) rs1535 and rs174448 in the fatty acid desaturase ( FADS ) gene cluster have opposite effects on erythrocyte LCPUFAs at 9 mo. Objective: To explore whether SNPs in FADS and elongase ( ELOVL ) genes were associated with school performance in a sex-specific manner, we performed a Mendelian randomization study using data from the Optimal well-being, development and health for Danish children through a healthy New Nordic Diet (OPUS) School Meal Study with 765 Danish schoolchildren 8-11 y old. Design: Associations between selected FADS1/2 SNPs (rs1535, rs174448, and rs174468) and ELOVL5 rs2397142, whole-blood fatty acid composition, and performance in the d2 Test of Attention and a reading test were analyzed in multiple regression models including all SNPs, SNP-sex interactions, and covariates related to testing conditions. Results: FADS , rs1535 minor allele carriage associated with lower whole-blood arachidonic acid ( P ≤ 0.002), and minor alleles of rs174448 tended to associate with lower docosahexaenoic acid (DHA) ( P = 0.052). We identified sex interactions in 50% of the SNP performance sets. Sex-dependent associations were observed for rs174448 and rs1535 on the d2 Test of Attention outcomes ( P < 0.03) and for the associations between reading scores and rs174448 and rs2397142 ( P < 0.01). All of the sex-specific analyses showed associations in opposite directions in girls and boys. The minor allele carriage of rs174448 was associated with lower d2 Test of Attention performance ( P < 0.02) and reading scores ( P < 0.001) in boys but with better reading scores in girls ( P ≤ 0.002). The associations were consistently the opposite for rs1535 minor allele carriage ( P < 0.05). Associations with

Refugee children and their families constitute a vulnerable group regarding health and access to care. In a register-based cohort design, we examined differences in uptake of immunisations and child health examinations between refugee children and Danish-born children, including predictors of uptake among refugee children. Refugee children (n = 16,701) who, between January 1993 and December 2010, obtained residency permits in Denmark were included and matched in a 1:6 ratio on age and sex with Danish-born children (n = 100,206). Personal identification numbers were cross-linked to the National Danish Health Service Register, identifying all contacts for immunisation and child health examinations. We estimated hazard ratios (HR) of uptake. Refugee children had a lower uptake of all immunisations compared to Danish-born children. The lowest uptake was found for immunisation against diphtheria, tetanus, pertussis and polio (HR = 0.50; 95 % confidence interval (CI) 0.48-0.51). Participation in child health examinations was also lower among refugee children with the lowest at the last child health examination at age 5 (HR = 0.48; 95 % CI 0.47-0.50). Adjusting the analysis for parental income increased the HRs by 10-20 %. This Danish register-based study using nationwide data revealed a lower uptake of routine immunisations and child health examinations among refugee children compared to Danish-born children. •Uptake of immunisation and child health examination is associated with low household income, unemployment and low educational status among the parents. •Uptake may be even lower among refugee families as they constitute a vulnerable group regarding access to healthcare. What is New: •Refugee children had lower uptake of immunisations and child health examinations compared to Danish-born children. •Several predictors of uptake were identified including region of origin and duration of residence.

2013-11-01

A potential link between breast implants and anaplastic large-cell lymphoma (ALCL) has been suggested. We examined lymphoma occurrence in a nationwide cohort of 19,885 Danish women who underwent breast implant surgery during 1973-2010. Standardized incidence ratios (SIR), with 95% confidence intervals (CI), for ALCL and lymphoma overall associated with breast implantation were calculated. During 179,246 person-years of follow-up, we observed 31 cases of lymphoma among cohort members. No cases of ALCL were identified. SIRs for ALCL and lymphoma overall were zero (95% CI, 0-10.3) and 1.20 (95% CI, 0.82-1.70), respectively. In our nationwide cohort study, we did not find an increased risk of lymphoma in general, or ALCL in particular, among Danish women who underwent breast implantation. However, our evaluation of ALCL risk was limited by the rarity of the disease. Our results do not support an association between breast implants and ALCL and are consistent with other studies on cancer risk and breast implants. ©2013 AACR.

Association between nationality and occupational injury risk on Danish non-passenger merchant ships.

Maritime occupational accidents can be determined by several factors, among which human characteristics play a crucial role. Worker's safety behaviour depends on individual physical and mental characteristics as well as on his/her social and cultural background. The aim of this study is to investigate the frequency of workplace injuries in the Danish merchant fleet in the period 2010-2012, and to characterise its nationality dependence. Occupational injuries data reported from ships registered in the Danish International Ship Register to the Danish Maritime Authority were collected. Publicly available employment data were used to calculate the cumulative incidence rates for Danish, non-Danish European Union (EU) and non-EU employees working on non-passenger ships. Crude injury rates and rates adjusted for occupational status were statistically compared. The majority of accidents happened to Danish and non-EU workers on non-passenger ships. The injury rate varied around 70 per 1000 among Danish seafarers, while the rate for non-Danish employees was about 30 per 1000. Crude and adjusted relative risk was found significantly lower for EU (0.33-0.46;0.26-0.39) and for non-EU (0.41-0.53; 0.54-0.65) workers compared to Danish seafarers. The difference decreased, but remained significant in most cases for serious injuries. Occupational injury rates show considerable nationality differences as reported from non-passenger ships registered under the Danish flag. The differences can only be partly explained by varying reporting practices. The findings confirm the results of previous studies and point out the need for effective interventions in the high-risk groups.

This study aimed to investigate associations between work postures, lifting at work, shift work, work hours, and job strain and the risk of sick leave during pregnancy from 10-29 completed pregnancy weeks in a large cohort of Danish pregnant women. Data from 51 874 pregnancies in the Danish National Birth Cohort collected between 1996-2002 were linked to the Danish Register for Evaluation of Marginalization. Exposure information was based on telephone interviews. Hazard ratios (HR) with 95% confidence intervals (95% CI) were calculated by Cox regression analysis, using time of first episode of sick leave as the primary outcome. We found statistically significant associations between all the predictors and risk of sick leave; for non-sitting work postures (HRrange 1.55-2.79), cumulative lifting HRtrend 1.29, 95% CI 1.26-1.31, shift work (HRevening 1.90, 95% CI 1.73-2.09, HRnight 1.52, 95% CI 1.15-2.01), monthly night shifts HRtrend 1.12, 95% CI 1.11-1.14, increasing weekly work hours HRtrend 0.93, 95% CI 0.91-0.95 and high job strain HR 1.52, 95% CI 1.42-1.63. Some exposures influenced HR in either a positive or negative time-dependent way. Our results support previous findings and suggest that initiatives to prevent sick leave during pregnancy could be based on work conditions. Preventive measures may have important implications for pregnant women and workplaces.

Air pollution from traffic and cancer incidence: a Danish cohort study

PubMed Central

2011-01-01

Background Vehicle engine exhaust includes ultrafine particles with a large surface area and containing absorbed polycyclic aromatic hydrocarbons, transition metals and other substances. Ultrafine particles and soluble chemicals can be transported from the airways to other organs, such as the liver, kidneys, and brain. Our aim was to investigate whether air pollution from traffic is associated with risk for other cancers than lung cancer. Methods We followed up 54,304 participants in the Danish Diet Cancer and Health cohort for 20 selected cancers in the Danish Cancer Registry, from enrolment in 1993-1997 until 2006, and traced their residential addresses from 1971 onwards in the Central Population Registry. We used modeled concentration of nitrogen oxides (NOx) and amount of traffic at the residence as indicators of traffic-related air pollution and used Cox models to estimate incidence rate ratios (IRRs) after adjustment for potential confounders. Results NOx at the residence was significantly associated with risks for cervical cancer (IRR, 2.45; 95% confidence interval [CI], 1.01;5.93, per 100 μg/m3 NOx) and brain cancer (IRR, 2.28; 95% CI, 1.25;4.19, per 100 μg/m3 NOx). Conclusions This hypothesis-generating study indicates that traffic-related air pollution might increase the risks for cervical and brain cancer, which should be tested in future studies.

To measure the effect of organic food conversion projects on the percentage of organic food used in Danish public kitchens participating in the Danish Organic Action Plan 2020. The current longitudinal study was based on measurements of organic food percentages in Danish public kitchens before and after kitchen employees participated in conversion projects. Public kitchens participating in the nine organic food conversion projects under the Danish Organic Action Plan 2020, initiated during autumn 2012 and spring 2013 and completed in summer 2015. A total of 622 public kitchens. The average (median) increase in organic food percentage from baseline to follow-up was 24 percentage points (P<0·001) during an overall median follow-up period of 1·5 years. When analysing data according to public kitchen type, the increase remained significant for seven out of eight kitchens. Furthermore, the proportion of public kitchens eligible for the Organic Cuisine Label in either silver (60-90 % organic food procurement) or gold (90-100 % organic food procurement) level doubled from 31 % to 62 %, respectively, during the conversion period. Conversion project curriculum mostly included elements of 'theory', 'menu planning', 'network' and 'Organic Cuisine Label method' to ensure successful implementation. The study reports significant increases in the level of organic food procurement among public kitchens participating in the Danish Organic Action Plan 2020. Recommendations for future organic conversion projects include adding key curriculum components to the project's educational content and measuring changes in organic food percentage to increase the chances of successful implementation.

From 2012-2015, the Departments of Obstetrics and Gynecology and of Pediatrics at the University of Copenhagen conducted a project, "Internationalization at Home ", offering clinical teaching in English. The project allowed international students to work with Danish speaking students in a clinical setting. Using semi-quantitative questionnaires to 89 clinicians about use of English and need for training, this paper considers if Danish clinical doctors are prepared to teach in English. The majority self-assessed their English proficiency between seven and eight on a 10 unit visual analogue scale, with 10 equivalent to working in Danish, while 15 % rated five or less. However, one-fourth found teaching and writing in English to be twice as difficult than in Danish, and 12 % rated all teaching tasks in English at four or less compared to Danish. The self-assessed need for additional English skills was perceived low. Teaching in English was rated as 30 % more difficult than in Danish, and a significant subgroup of doctors had difficulties in all forms of communication in English, resulting in challenges when introducing international students in non-native English speaking medical departments.

To investigate psychosocial work environment and stress in Danish symphony orchestra musicians. This was a cross-sectional questionnaire survey of psychosocial work factors and stress symptoms among 441 musicians in six Danish symphony orchestras. The response rate was 78% (n = 342). The questions were from COPSOQ (Copenhagen Psychosocial Questionnaire). Mean values of 19 COPSOQ-scales were compared by gender and instrument group. The results for the musicians were compared with results for the general Danish work force (COPSOQ database). Female musicians reported higher work demands and higher stress symptoms than their male colleagues. Between instrument groups, 2nd violinists seemed to be of particular risk compared with the other instrumental groups in aspects of work pace, work organization, and content, whereas 1st violinists perceived higher emotional stress compared with 2nd violinists. The musicians' experience of increased work demands as well as deteriorated, work organization and job content, interpersonal relations and leadership, and work-individual interface was significantly associated with increasing stress symptoms. Compared to the general workforce independently of gender, Danish symphony orchestra musicians reported higher emotional demands, lower influence, lower social support, lower sense of community, and lower job satisfaction. However, the musicians reported a higher commitment to the workplace. The findings indicate a more demanding psychosocial work environment exposure among symphony orchestra musicians than among Danish workers in general. Critical results are the relatively high work demands, low influence, and low social support, females being of higher risk than males.

In 2010 the five Danish regions and the National Institute of Public Health at the University of Southern Denmark conducted a national representative health survey among the adult population in Denmark. This paper describes the study design and the sample and study population as well as the content of the questionnaire. The survey was based on five regional stratified random samples and one national random sample. The samples were mutually exclusive. A total of 298,550 individuals (16 years or older) were invited to participate. Information was collected using a mixed mode approach (paper and web questionnaires). A questionnaire with a minimum of 52 core questions was used in all six subsamples. Calibrated weights were computed in order to take account of the complex survey design and reduce non-response bias. In all, 177,639 individuals completed the questionnaire (59.5%). The response rate varied from 52.3% in the Capital Region of Denmark sample to 65.5% in the North Denmark Region sample. The response rate was particularly low among young men, unmarried people and among individuals with a different ethnic background than Danish. The survey was a result of extensive national cooperation across sectors, which makes it unique in its field of application, e.g. health surveillance, planning and prioritizing public health initiatives and research. However, the low response rate in some subgroups of the study population can pose problems in generalizing data, and efforts to increase the response rate will be important in the forthcoming surveys.

We investigated whether induced abortion is associated with breast cancer when lifestyle confounders, including smoking and alcohol consumption, are adjusted for. Design. Prospective cohort study. Danish women from the Diet, Cancer and Health study. A total of 25,576 women. We obtained exposure data from baseline questionnaires filled in by the women between 1993 and 1997. Information on breast cancer and emigration was retrieved from Danish national registries. The study power was approximately 85% when applying a minimum detection hazard ratio of 1.2. Long-term effects of induced abortion on the risk of breast cancer among women above 50 years of age. During a follow up of approximately 12 years, 1215 women were diagnosed with breast cancer. When comparing parous women who had an abortion with parous women who never had an abortion, there was no association between breast cancer risk and induced abortion (ever vs. never), with a hazard ratio 0.95 (95% confidence interval 0.83-1.09), regardless of whether the abortion occurred before the first birth (hazard ratio 0.86; 95% confidence interval 0.65-1.14), or after the first birth (hazard ratio 0.97; 95% confidence interval 0.84-1.13). Our study did not show evidence of an association between induced abortion and breast cancer risk. © 2013 The Authors Acta Obstetricia et Gynecologica Scandinavica © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

Orthotics and Prosthetics User's Survey (OPUS) was developed to measure patient satisfaction in Prosthetic and Orthotic (P&O) field. To translate the satisfaction assessment module of OPUS (OPUS-SM) into Persian language (Persian OPUS-SM) and investigate its psychometric properties. For cross-cultural adaptation of the OPUS-SM, the guideline suggested by the World Health Organization was recruited. A sample of 116 Persian-speaking people who received P&O devices and services, participated in this study. During the first session, participants filled out the Persian OPUS-SM and the Visual Analog Scale (VAS) regarding their satisfaction from delivered devices and services. Drawing from the above sample of 116 participants, 41 participants retook the Persian OPUS-SM 5-7 days after their first time. The results of the first and second administration sessions were analyzed to assess internal consistency, test-retest reliability, item-subscale correlation, minimal detectable change, floor and ceiling effects, criterion validity, and dimensionality of the Persian OPUS-SM. The Cronbach's alphas of the Persian OPUS-SM were 0.71 and 0.89 for device and service satisfaction subscales, respectively. The intraclass correlation coefficients were 0.76 and 0.90 for device and service satisfaction subscales, respectively. The SEM and MDC for device satisfaction were 6.21 and ±17.21, respectively. The SEM and MDC for service satisfaction were 2.25 and ±6.22, respectively. There was a strong correlation between VAS and satisfaction subscales of the Persian OPUS-SM. Dimensionality assessment revealed that Persian OPUS-SM is a unidimensional measure. The adapted and translated Persian OPUS-SM is a reliable and validated measure. Copyright © 2016 Elsevier Inc.

Bovine renal lipofuscinosis (BRL) is an incidental finding in cattle at slaughter. Condemnation of the kidneys as unfit for human consumption was until recently considered the only implication of BRL. Recent studies have indicated a negative influence on the health of affected animals. The present study investigated the prevalence, genetics and effect of BRL on milk yield and weight at slaughter. BRL status of slaughter cattle was recorded at four abattoirs during a 2-year-period. Data regarding breed, age, genetic descent, milk yield and weight at slaughter were extracted from the Danish Cattle Database. The prevalence of BRL was estimated stratified by breed and age-group. Furthermore, total milk yield, milk yield in last full lactation and weight at slaughter were compared for BRL-affected and non-affected Danish Holsteins and Danish Red cattle. 433,759 bovines were slaughtered and 787 of these had BRL. BRL was mainly diagnosed in Danish Red, Danish Holstein and crossbreds. The age of BRL affected animals varied from 11 months to 13 years, but BRL was rarely diagnosed in cattle less than 2 years of age.The total lifelong energy corrected milk (ECM) yields were 3,136 and 4,083 kg higher for BRL affected Danish Red and Danish Holsteins, respectively. However, the median life span of affected animals was 4.9 months longer, and age-corrected total milk yield was 1,284 kg lower for BRL affected Danish Red cows. These cows produced 318 kg ECM less in their last full lactation. Weight at slaughter was not affected by BRL status.The cases occurred in patterns consistent with autosomal recessive inheritance and several family clusters of BRL were found. Analysis of segregation ratios demonstrated the expected ratio for Danish Red cattle, but not for Danish Holsteins. The study confirmed that BRL is a common finding in Danish Holsteins and Danish Red cattle at slaughter. The disorder is associated with increased total milk yield due to a longer production life. However, a

The nationwide Danish Testicular Cancer database consists of a retrospective research database (DaTeCa database) and a prospective clinical database (Danish Multidisciplinary Cancer Group [DMCG] DaTeCa database). The aim is to improve the quality of care for patients with testicular cancer (TC) in Denmark, that is, by identifying risk factors for relapse, toxicity related to treatment, and focusing on late effects. All Danish male patients with a histologically verified germ cell cancer diagnosis in the Danish Pathology Registry are included in the DaTeCa databases. Data collection has been performed from 1984 to 2007 and from 2013 onward, respectively. The retrospective DaTeCa database contains detailed information with more than 300 variables related to histology, stage, treatment, relapses, pathology, tumor markers, kidney function, lung function, etc. A questionnaire related to late effects has been conducted, which includes questions regarding social relationships, life situation, general health status, family background, diseases, symptoms, use of medication, marital status, psychosocial issues, fertility, and sexuality. TC survivors alive on October 2014 were invited to fill in this questionnaire including 160 validated questions. Collection of questionnaires is still ongoing. A biobank including blood/sputum samples for future genetic analyses has been established. Both samples related to DaTeCa and DMCG DaTeCa database are included. The prospective DMCG DaTeCa database includes variables regarding histology, stage, prognostic group, and treatment. The DMCG DaTeCa database has existed since 2013 and is a young clinical database. It is necessary to extend the data collection in the prospective database in order to answer quality-related questions. Data from the retrospective database will be added to the prospective data. This will result in a large and very comprehensive database for future studies on TC patients.

This population-based longitudinal study aimed to investigate trends in use of inhaled corticosteroids (ICS) and determinants of ICS use in young Danish adults with asthma. 106 757 users, aged 18-44 years, of anti-asthmatic drugs were identified in the Danish Register of Medical Product Statistics during 1997-2006. One year prevalences of ICS use were calculated in categories of gender, age, and annual consumption of inhaled beta-2-agonists (IBA) in defined daily doses (DDD) per year. Determinants of ICS use were estimated by logistic regression models. The one year prevalence of ICS use was constant, approximately 64%, during 1997-2000. An annual increase was observed from 67% in 2001 to 77% in 2006. This trend also existed when stratifying on gender, age and IBA use. Using 1997 as baseline, the adjusted odds ratios (ORs) of ICS use in 2000 was 0.98 (95% CI 0.96-1.01) compared to 1.12 (95% CI 1.09-1.15) in 2001, and 1.81 (95% CI 1.75-1.87) in 2006. Other determinants of high ICS use were female gender, young age, and high annual IBA consumption. Among those using at least 400 DDD of IBA per year (corresponding to 4.4 powder inhalations daily), nearly 20% had no ICS prescriptions in 2006. Treatment with ICS among young Danish adult asthmatics has increased since 2001. This apparent improvement was associated with the introduction of fixed dose combination inhalers with ICS and inhaled long-acting beta-2-agonists. However, there is still room for improvement.

Danish auroral science history

Stauning, P.

2011-01-01

Danish auroral science history begins with the early auroral observations made by the Danish astronomer Tycho Brahe during the years from 1582 to 1601 preceding the Maunder minimum in solar activity. Included are also the brilliant observations made by another astronomer, Ole Rømer, from Copenhagen in 1707, as well as the early auroral observations made from Greenland by missionaries during the 18th and 19th centuries. The relations between auroras and geomagnetic variations were analysed by H. C. Ørsted, who also played a vital role in the development of Danish meteorology that came to include comprehensive auroral observations from Denmark, Iceland and Greenland as well as auroral and geomagnetic research. The very important auroral investigations made by Sophus Tromholt are outlined. His analysis from 1880 of auroral observations from Greenland prepared for the significant contributions from the Danish Meteorological Institute, DMI, (founded in 1872) to the first International Polar Year 1882/83, where an expedition headed by Adam Paulsen was sent to Greenland to conduct auroral and geomagnetic observations. Paulsen's analyses of the collected data gave many important results but also raised many new questions that gave rise to auroral expeditions to Iceland in 1899 to 1900 and to Finland in 1900 to 1901. Among the results from these expeditions were 26 unique paintings of the auroras made by the artist painter, Harald Moltke. The expedition to Finland was headed by Dan la Cour, who later as director of the DMI came to be in charge of the comprehensive international geomagnetic and auroral observations made during the Second International Polar Year in 1932/33. Finally, the article describes the important investigations made by Knud Lassen during, among others, the International Geophysical Year 1957/58 and during the International Quiet Sun Year (IQSY) in 1964/65. With his leadership the auroral and geomagnetic research at DMI reached a high international

It is widely believed that autoimmune hepatitis accumulates in families, but the degree of familial clustering has not been clarified. We conducted a population-based study on the family occurrence of autoimmune hepatitis. Through Danish nationwide registries we identified 8,582 first-degree and 9,230 second-degree relatives of index patients diagnosed with autoimmune hepatitis in 1994-2015; and 64 co-twins of index patients diagnosed with autoimmune hepatitis in 1977-2011. For first- and second-degree relatives we calculated the sex- and age-adjusted standardized incidence ratio of autoimmune hepatitis relative to the general population, and we calculated the cumulative risk, i.e. the cumulative incidence, of developing autoimmune hepatitis from the time of the index patient's diagnosis. For co-twins, we estimated the standardized incidence ratio and the concordance rate of autoimmune hepatitis. In first-degree relatives, there were six incident autoimmune hepatitis diagnoses during 64,020 years of follow-up: the standardized incidence ratio was 4.9 (95% CI 1.8-10.7), and the 10-year cumulative risk was 0.10% (95% CI 0.04-0.23). In the second-degree relatives, there were no incident autoimmune hepatitis diagnoses (expected number assuming incidence rate as in the Danish general population = 0.8). In the co-twins, there was one incident autoimmune hepatitis diagnosis during 1,112 years of follow-up, and the standardized incidence ratio was 53.9 (95% CI 1.4-300.4). The probandwise concordance rate, a measure of heritability, was higher in monozygotic than in dizygotic twins (8.7% [95% CI 1.1-28.0] vs. 0%). This nationwide study indicates that only first-degree relatives of index patients with autoimmune hepatitis are at increased risk of autoimmune hepatitis from the time of the index patient's diagnosis, but the absolute risk is very low. Autoimmune hepatitis is a chronic liver disease caused by a dysfunctional immune system. It is widely believed that autoimmune

The purpose of this study was to investigate cultural differences between Danish and American children at 2 and 3 years as measured with the developmental test Bayley-III, and to investigate the Bayley-III Language Scale validity. The Danish children (N = 43) were tested with the Bayley-III and their parents completed an additional language questionnaire (the MacArthur-Bates CDI). Results showed that scores from the Danish children did not differ significantly from the American norms on the Cognitive or Motor Scale, but the Danish sample scored significantly higher on the Language Scale. A comparison of the Bayley-III Language subtests with the CDI showed that the two measures correlated significantly, but the percentile score from the CDI was significantly higher than the percentile score from the Bayley-III Language subtests. This could be because the two instruments measure slightly different areas of language development, or because the Bayley-III overestimates language development in Danish children. However, due to the limitations of the current study, further research is needed to clarify this issue. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Objectives Studies comprising Danish Seventh-day Adventists (SDAs) and Danish Baptists found that members have a lower risk of chronic diseases including cancer. Explanations have pointed to differences in lifestyle, but detailed aetiology has only been sparsely examined. Our objective was to investigate the incidence of sexually transmitted diseases (STDs) among Danish SDAs and Baptists as a proxy for cancers related to sexual behaviour. Methods We followed the Danish Cohort of Religious Societies from 1977 to 2009, and linked it with national registers of all inpatient and outpatient care contacts using the National Patient Register. We compared the incidence of syphilis, gonorrhoea and chlamydia among members of the cohort with the general population. Results The cohort comprised 3119 SDA females, 1856 SDA males, 2056 Baptist females and 1467 Baptist males. For the entire cohort, we expected a total of 32.4 events of STD, and observed only 9. Female SDAs and Baptists aged 20–39 years had significant lower incidence of chlamydia (both p<0.001). Male SDAs and Baptists aged 20–39 years also had significant lower incidence of chlamydia (p<0.01 and p<0.05, respectively). No SDA members were diagnosed with gonorrhoea, when 3.4 events were expected, which, according to Hanley's ‘rule of three’, is a significant difference. No SDA or Baptist was diagnosed with syphilis. Conclusions The cohort shows significant lower incidence of STD, most likely including human papillomavirus, which may partly explain the lower incidence of cancers of the cervix, rectum, anus, head and neck.

The Danish National Birth Cohort (DNBC) contains comprehensive information on diet, lifestyle, constitutional and other major characteristics of women during pregnancy. It provides a unique source for studies on health consequences of gestational diabetes mellitus. Our aim was to identify and validate the gestational diabetes mellitus cases in the cohort. We extracted clinical information from hospital records for 1609 pregnancies included in the Danish National Birth Cohort with a diagnosis of diabetes during or before pregnancy registered in the Danish National Patient Register and/or from a Danish National Birth Cohort interview during pregnancy. We further validated the diagnosis of gestational diabetes mellitus in 2126 randomly selected pregnancies from the entire Danish National Birth Cohort. From the individual hospital records, an expert panel evaluated gestational diabetes mellitus status based on results from oral glucose tolerance tests, fasting blood glucose and Hb1c values, as well as diagnoses made by local obstetricians. The audit categorized 783 pregnancies as gestational diabetes mellitus, corresponding to 0.89% of the 87 792 pregnancies for which a pregnancy interview for self-reported diabetes in pregnancy was available. From the randomly selected group the combined information from register and interviews could correctly identify 96% (95% CI 80-99.9%) of all cases in the entire Danish National Birth Cohort population. Positive predictive value, however, was only 59% (56-61%). The combined use of data from register and interview provided a high sensitivity for gestational diabetes mellitus diagnosis. The low positive predictive value, however, suggests that systematic validation by hospital record review is essential not to underestimate the health consequences of gestational diabetes mellitus in future studies. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

The positive predictive value of an infective endocarditis diagnosis is approximately 80% in the Danish National Patient Registry. However, since infective endocarditis is a heterogeneous disease implying long-term intravenous treatment, we hypothesiszed that the positive predictive value varies by length of hospital stay. A total of 100 patients with first-time infective endocarditis in the Danish National Patient Registry were identified from January 2010 - December 2012 at the University hospital of Aarhus and regional hospitals of Herning and Randers. Medical records were reviewed. We calculated the positive predictive value according to admission length, and separately for patients with a cardiac implantable electronic device and a prosthetic heart valve using the Wilson score method. Among the 92 medical records available for review, the majority of the patients had admission length ⩾2 weeks. The positive predictive value increased with length of admission. In patients with admission length <2 weeks the positive predictive value was 65% while it was 90% for admission length ⩾2 weeks. The positive predictive value was 81% for patients with a cardiac implantable electronic device and 87% for patients with a prosthetic valve. The positive predictive value of the infective endocarditis diagnosis in the Danish National Patient Registry is high for patients with admission length ⩾2 weeks. Using this algorithm, the Danish National Patient Registry provides a valid source for identifying infective endocarditis for research.

Type 1 diabetes mellitus (T1D) and multiple sclerosis (MS) contribute considerably to the burden of autoimmune diseases in young adults. Although HLA patterns of T1D and MS are considered mutually exclusive, individual and familial co-occurrence of the 2 diseases has been reported. To assess the co-occurrence of T1D and MS by estimating the risk for MS in patients with T1D and the risk for T1D in first-degree relatives of patients with MS. Two population-based disease registers, the Danish Hospital Discharge Register and the Danish Multiple Sclerosis Register were used to identify patients with T1D, defined as patients in whom diabetes was diagnosed before age 20 years (N = 6078), and patients with MS (N = 11 862). First-degree relatives (N = 14,771) of patients with MS were identified from family information in the Danish Civil Registration System. Patients with T1D and first-degree relatives of patients with MS were followed up for occurrence of MS and T1D, respectively, and the relative risks were expressed as standardized incidence ratios, that is, ratios of observed to expected numbers of outcomes based on national age, sex, and period-specific MS and T1D incidence rates. Patients with T1D were at more than 3-fold increased risk for development of MS (relative risk, 3.26; 95% confidence interval, 1.80-5.88; n = 11). First-degree relatives of patients with MS were at 63% increased risk (relative risk, 1.63; 95% confidence interval, 1.26-2.12; n = 56) for development of T1D. However, adjusting for familial relationship to patients with T1D reduced the excess risk to 44% (relative risk, 1.44; 95% confidence interval, 1.11-1.88; n = 56). The present nationwide cohort study demonstrates an intraindividual and, to a lesser degree, an intrafamilial co-occurrence of MS and T1D.

In recent years, the prevalence of contact allergy to isothiazolinones has reached epidemic levels. Few studies have presented data on occupations at risk of developing contact allergy to isothiazolinones. To present demographics and examine risk factors for sensitization to methylisothiazolinone (MI), methylchloroisothiazolinone (MCI) in combination with MI and benzisothiazolinone (BIT) in Danish dermatitis patients. A retrospective epidemiological analysis of data from three Danish hospitals departments was conducted. All patients consecutively patch tested with MI, MCI/MI and BIT between 2009 and 2013 were included. MI contact allergy showed a significantly increased trend in prevalence from 1.8% in 2009 to 4.2% in 2012 (p < 0.001). Females with facial dermatitis mainly drove the increase in 2012. Adjusted logistic regression analysis showed that MI sensitization was significantly associated with occupational exposures, hand and facial dermatitis, age > 40 years, and the occupational groups of tile setters/terrazzo workers, machine operators, and painters. MCI/MI contact allergy was significantly associated with the following high-risk occupations: painting, welding (blacksmiths), machine operating, and cosmetology. The occupational group of painting was frequent in the group of patients with BIT contact allergy. Several high-risk occupations for sensitization to isothiazolinones exist. Regulation on the allowed concentration of isothiazolinones, and especially MI, in both consumer products and industrial products is needed. © 2014 John Wiley & Sons A/S.

Introduction. The aim of this study was to estimate the significance of TSH, thyroid peroxidase antibody (TPOAb), and mild (subclinical) hypothyroidism in women from The Danish General Suburban Population Study (GESUS) on the number of children born, the number of pregnancies, and the number of spontaneous abortions. Methods. Retrospective cross sectional study of 11254 women participating in GESUS. Data included biochemical measurements and a self-administrated questionnaire. Results. 6.7% had mild (subclinical) hypothyroidism and 9.4% prevalent hypothyroidism. In women with mild hypothyroidism TPOAb was significantly elevated and age at first child was older compared to controls. TSH and TPOAb were negatively linearly associated with the number of children born and the number of pregnancies in the full cohort in age-adjusted and multiadjusted models. TSH or TPOAb was not associated with spontaneous abortions. Mild (subclinical) hypothyroidism was associated with a risk of not having children and a risk of not getting pregnant in age-adjusted and multiadjusted models. Prevalent hypothyroidism was not associated with the number of children born, the number of pregnancies, or spontaneous abortions. Conclusion. Impaired fertility is associated with TSH, TPOAb, and mild (subclinical) hypothyroidism in a Danish population of women. PMID:26351582

Testosterone is an important hormone in the sexual differentiation of the brain, contributing to differences in cognitive abilities between males and females. For instance, studies in clinical populations such as females with congenital adrenal hyperplasia (CAH) who are exposed to high levels of androgens in utero support arguments for prenatal testosterone effects on characteristics such as visuospatial cognition and behaviour. The comparison of opposite-sex (OS) and same-sex (SS) twin pairs can be used to help establish the role of prenatal testosterone. However, although some twin studies confirm a masculinizing effect of a male co-twin regarding for instance perception and cognition it remains unclear whether intra-uterine hormone transfer exists in humans. Our aim was to test the potential influences of testosterone on academic performance in OS twins. We compared ninth-grade test scores and teacher ratings of OS (n = 1812) and SS (n = 4054) twins as well as of twins and singletons (n = 13,900) in mathematics, physics/chemistry, Danish, and English. We found that males had significantly higher test scores in mathematics than females (.06–.15 SD), whereas females performed better in Danish (.33–.49 SD), English (.20 SD), and neatness (.45–.64 SD). However, we did not find that OS females performed better in mathematics than SS and singleton females, nor did they perform worse either in Danish or English. Scores for OS and SS males were similar in all topics. In conclusion, this study did not provide evidence for a masculinization of female twins with male co-twins with regard to academic performance in adolescence. PMID:25655669

We compared ninth-grade test scores and teacher ratings of OS (n=1812) and SS (n=4054) twins as well as of twins and singletons (n=13,900) in mathematics, physics/chemistry, Danish, and English. We found that males had significantly higher test scores in mathematics than females (.06-.15 SD), whereas females performed better in Danish (.33-.49 SD), English (.20 SD), and neatness (.45-.64 SD). However, we did not find that OS females performed better in mathematics than SS and singleton females, nor did they perform worse either in Danish or English. Scores for OS and SS males were similar in all topics. In conclusion, this study did not provide evidence for a masculinization of female twins with male co-twins with regard to academic performance in adolescence. Copyright © 2015 Elsevier Inc.

The aim was to explore the impact of occupation on chronic obstructive pulmonary disease (COPD) in a cross-sectional population-based study among subjects aged 45 to 84 years. In a stratified sampling 89 general practitioners practices (GPP) in Denmark recruited 3106 males and 1636 females through the Danish Civil Registration System. COPD was defined by spirometry by the 2.5(th)-centile Lower Limit of Normal of FEV1 and FEV1/FVC. Information about smoking, occupational exposure and the respective occupations were obtained from questionnaires. Occupations followed the Danish adaptation of The International Standard Classification of Occupations, revision 1988 (DISCO-88). Exposure to vapour, gas, dust (organic and inorganic), and fume (VGDF) in each occupation (yes/no) was evaluated by two independent specialist in occupational medicine. Exposures were divided in no, low, medium, and high exposure as 0, < 5, 5-14, and ≥ 15 years in the job, respectively. Data was analysed by a mixed random effect logistic regression model. The age-standardised COPD study prevalence was 5.0%. Of 372 DISCO-88 codes 72 were identified with relevant exposure to VGDF. 46% of the participants reported at least one occupation with VGDF exposure. Adjusted for smoking, age, sex, and GPP a dose-dependent association of COPD was found among workers in jobs with high organic dust exposure, with OR 1.56 (95% CI 1.09-2.24). Restricted to agriculture the OR was 1.59 (95% CI: 1.08-2.33). No association was observed for workers in jobs with inorganic dust, fume/gas, or vapour exposures. In summary, occupational organic dust exposure was associated to the prevalence of COPD.

Do women who don't succeed in giving birth after an infertility evaluation have a higher risk of psychiatric disorders compared with women who do? The results indicated that being unsuccessful in giving birth after an infertility evaluation could be an important risk factor for psychiatric disorders. Several studies have investigated the association between fertility treatment and psychological distress, but the results from these studies show substantial variation and lack of homogeneity that may be due to methodological limitations. A retrospective cohort study was designed using data from a cohort of 98 320 Danish women evaluated for fertility problems during 1973-2008 and linked to several Danish population-based registries. All women were followed from the date of first infertility evaluation until date of hospitalization for the psychiatric disorder in question, date of emigration, date of death or 31 December 2008, whichever occurred first. Owing to the precise linkage between the infertility cohort and the Danish population-based registries, using the unique Danish personal identification number, virtually no women were lost to follow-up. Information on reproductive status for all women in the infertility cohort was obtained by linkage to the Danish Medical Birth Registry. A total of 53 547 (54.5%) women gave birth after the initial infertility evaluation, whereas 44 773 (45.5%) women did not gave birth after the evaluation. To determine psychiatric disorders diagnosed in the women after enrolment in the infertility cohort, the cohort was linked to the Danish Psychiatric Central Registry. A total of 4633 women were hospitalized for a psychiatric disorder. The Cox proportional hazard regression model was applied to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) for the association between parity status after the initial infertility evaluation and risk of hospitalization for various groups of psychiatric disorders, including

To develop a simple self-administered questionnaire identifying individuals with undiagnosed diabetes with a sensitivity of 75% and minimizing the high-risk group needing subsequent testing. A population-based sample (Inter99 study) of 6,784 individuals aged 30-60 years completed a questionnaire on diabetes-related symptoms and risk factors. The participants underwent an oral glucose tolerance test. The risk score was derived from the first half and validated on the second half of the study population. External validation was performed based on the Danish Anglo-Danish-Dutch Study of Intensive Treatment in People with Screen Detected Diabetes in Primary Care (ADDITION) pilot study. The risk score was developed by stepwise backward multiple logistic regression. The final risk score included age, sex, BMI, known hypertension, physical activity at leisure time, and family history of diabetes, items independently and significantly (P<0.05) associated with the presence of previously undiagnosed diabetes. The area under the receiver operating curve was 0.804 (95% CI 0.765-0.838) for the first half of the Inter99 population, 0.761 (0.720-0.803) for the second half of the Inter99 population, and 0.803 (0.721-0.876) for the ADDITION pilot study. The sensitivity, specificity, and percentage that needed subsequent testing were 76, 72, and 29%, respectively. The false-negative individuals in the risk score had a lower absolute risk of ischemic heart disease compared with the true-positive individuals (11.3 vs. 20.4%; P<0.0001). We developed a questionnaire to be used in a stepwise screening strategy for type 2 diabetes, decreasing the numbers of subsequent tests and thereby possibly minimizing the economical and personal costs of the screening strategy.

Achieving interoperability in health is a challenge and requires standardization. The newly developed HL7 standard: Fast Healthcare Interoperability Resources (FHIR) promises both flexibility and interoperability. This study investigates the feasibility of expressing a Danish microbiology message model content in FHIR to explore whether complex in-use legacy models can be migrated and what challenges this may pose. The Danish microbiology message model (the DMM) is used as a case to illustrate challenges and opportunities accosted with applying the FHIR standard. Mapping of content from DMM to FHIR was done as close as possible to the DMM to minimize migration costs except when the structure of the content did not fit into FHIR. From the DMM a total of 183 elements were mapped to FHIR. 75 (40.9%) elements were modeled as existing FHIR elements and 96 (52.5%) elements were modeled as extensions and 12 (6.6%) elements were deemed unnecessary because of build-in FHIR characteristics. In this study, it was possible to represent the content of a Danish message model using HL7 FHIR.

Working as a physician at an oncology department has some distinctive characteristics that may lead to a stressful work environment. The present study was conducted to provide a nationwide description of the work conditions of all oncologists in Denmark. By comparing the results of the present study with those of a similar study carried out in 2006, the aim was furthermore to elucidate changes in the psychosocial work environment over time. From May to September 2009, 330 physicians employed at six oncology centres and seven community based oncology departments were invited to participate in a survey based on the short version of the COPSOQ II questionnaire. The results were compared with data from a representative section of Danish employees and with data from the 2006 survey. Two hundred and twenty of the 330 invited physicians returned the questionnaire (response rate 67%). Concerning the aspects quantitative demands, work pace, emotional demands, influence, burnout and stress, the oncologists reported worse work conditions than the average Danish employee. However, with regard to possibilities for development, meaning of work and commitment to workplace, the oncologists reported better work conditions. Between 2006 and 2009, substantial improvement was seen concerning several of the assessed work environment aspects within the group of young physicians at the oncology centres. Though substantial improvement of the work conditions has been achieved between 2006 and 2009, certain aspects of the psychosocial work environment at Danish oncology departments still require attention.

The Danish Adoption Register was established in 1963-1964 to explore the genetic and environmental contribution to familial aggregation of schizophrenia. The register encompass information on all 14,425 non-familial adoptions of Danish children legally granted in Denmark 1924-1947. It includes name and date of birth of each adoptee and his or her biological and adoptive parents, date of transfer to adoptive parents and date of formal adoption. The linkage to biological and adoptive parents is close to complete, even biological fathers are registered for 91.4% of the adoptees. Adoption registers are a unique source allowing disentangling of genetic and familial environmental influences on traits, risk of diseases, and mortality.

Differences in the genetic architecture of inflammatory bowel disease between different European countries and ethnicities have previously been reported. In the present study, we wanted to assess the role of 11 newly identified UC risk variants, derived from a recent European UC genome wide association study (GWAS) (Franke et al., 2010), for 1) association with UC in the Nordic countries, 2) for population heterogeneity between the Nordic countries and the rest of Europe, and, 3) eventually, to drive some of the previous findings towards overall genome-wide significance. Eleven SNPs were replicated in a Danish sample consisting of 560 UC patients and 796 controls and nine missing SNPs of the German GWAS study were successfully genotyped in the Baltic sample comprising 441 UC cases and 1156 controls. The independent replication data was then jointly analysed with the original data and systematic comparisons of the findings between ethnicities were made. Pearson's χ2, Breslow-Day (BD) and Cochran-Mantel-Haenszel (CMH) tests were used for association analyses and heterogeneity testing. The rs5771069 (IL17REL) SNP was not associated with UC in the Danish panel. The rs5771069 (IL17REL) SNP was significantly associated with UC in the combined Baltic, Danish and Norwegian UC study sample driven by the Norwegian panel (OR = 0.89, 95% CI: 0.79-0.98, P = 0.02). No association was found between rs7809799 (SMURF1/KPNA7) and UC (OR = 1.20, 95% CI: 0.95-1.52, P = 0.10) or between UC and all other remaining SNPs. We had 94% chance of detecting an association for rs7809799 (SMURF1/KPNA7) in the combined replication sample, whereas the power were 55% or lower for the remaining SNPs.Statistically significant PBD was found for OR heterogeneity between the combined Baltic, Danish, and Norwegian panel versus the combined German, British, Belgian, and Greek panel (rs7520292 (P = 0.001), rs12518307 (P = 0.007), and rs2395609 (TCP11) (P = 0.01), respectively).No SNP reached genome

Thyroid hormones are essential for the normal development of the fetal brain, while hyperthyroidism in adults is associated with mood symptoms and reduced quality of life. In this study, we aimed to investigate the association and temporal relationship between hyperthyroidism and psychiatric morbidity. Register-based nationwide cohort study. Data on hyperthyroidism and psychiatric morbidity were obtained by record linkage of the Danish National Patient Registry and the Danish National Prescription Registry. A total of 2631 hyperthyroid individuals were identified and matched 1:4 with non-hyperthyroid controls and followed for a mean duration of 6 years (range 0-13). Logistic and Cox regression models were used to assess the risk of psychiatric morbidity before and after the diagnosis of hyperthyroidism respectively. BEFORE THE DIAGNOSIS OF HYPERTHYROIDISM, SUCH INDIVIDUALS HAD AN INCREASED RISK OF BEING HOSPITALIZED WITH PSYCHIATRIC DIAGNOSES (ODDS RATIO (OR): 1.33; 95% CI: 0.98-1.80) and an increased risk of being treated with antipsychotics (OR: 1.17; 95% CI: 1.00-1.38), antidepressants (OR: 1.13; 95% CI: 1.01-1.27), or anxiolytics (OR: 1.28; 95% CI: 1.16-1.42). After the diagnosis of hyperthyroidism, there was a higher risk of being hospitalized with psychiatric diagnoses (hazard ratio (HR): 1.51; 95% CI: 1.11-2.05) and an increased risk of being treated with antipsychotics (HR: 1.46; 95% CI: 1.20-1.79), antidepressants (HR: 1.54; 95% CI: 1.36-1.74), or anxiolytics (HR: 1.47; 95% CI: 1.27-1.69). Hyperthyroid individuals have an increased risk of being hospitalized with psychiatric diagnoses and being treated with antipsychotics, antidepressants, and anxiolytics, both before and after the diagnosis of hyperthyroidism.

A nutritionally adequate diet in childhood is important for health and resistance of allergies and infections. This study explored the effects of school meals rich in fish, vegetables and fibre on school attendance, asthma, allergies and illness in 797 Danish 8- to 11-year-old children. No comparable studies conducted in high-income settings have been identified. The OPUS School Meal Study was a cluster-randomised cross-over trial. Children from third and fourth grades at nine Danish schools received school meals or usual packed lunch (control) for two 3-month periods. Occurrence and duration of illnesses, asthma and allergies during the last 14 days were recorded by parental questionnaires at baseline and after each 3-month period. Self-reported well-being was assessed by visual analogue scales. The school meals did not affect school attendance, parent-reported occurrence or duration of asthma and allergies or self-reported well-being. The most common symptoms of illness were stomach pain (24%), headache (28%) and cold (24%). A slightly higher number of children experienced headaches in the school meal (27%) compared with the control period (22%) (P=0.02). However, subgroup analyses showed that this effect was only seen in children eating school meals in the classroom (P=0.007), and not in common dining areas (P=0.2). No effect was found on other symptoms of illness. Provision of nutritionally balanced school meals did not affect school attendance, asthma, allergies, illness or well-being in 8- to 11-year-old children. The slight increase in occurrence of headaches seems to be related to the physical eating environment.

Previous studies suggest that religious practice can have a positive effect on mental health, but may also have potential for harm. In Denmark, unique possibilities are available for studying the influence of religious practice on mental health: Denmark is characterized as a secular society and it is possible to follow members of religious societies in nationwide registers. In this study, we follow a cohort of Danish Seventh-day Adventists (SDA) and Baptists in a nationwide psychiatry register and compare the incidence in this cohort with the general population. We followed a cohort of 5,614 SDA and 3,663 Baptists in the Danish Psychiatric Central Register, which contained information on psychiatric hospitalizations from 1970 to 2009. Psychiatric disease incidence in the cohort was compared with that in the general Danish population as standardized incidence ratios and within-cohort comparisons were made with a Cox model. The cohort had decreased incidence of abuse disorders compared to the general population. Furthermore, among Baptists, decreased incidence of unipolar disorders among men and decreased incidence of schizophrenia among women were observed. Surprisingly, we observed an increased incidence rate of unipolar disorder among women. In this nationwide cohort study with 40 years of follow-up, we observed increased incidence rates of unipolar disorders among women and decreased rates of alcohol- and drug-related psychiatric disorders compared to the general Danish population. We have no mechanistic explanation for the increased incidence of unipolar disorders among women, but discuss several hypotheses that could explain this observation.

Determinants for employer-paid health insurance coverage: a population-based study of the Danish labour force.

PubMed

Christensen, Ann; Søgaard, Rikke

In 2002, the Danish tax law was changed, giving employees a tax exemption on supplemental, employer-paid health insurance. This might have conflicted with one of the key foundations of the healthcare system, namely equal access for equal needs. The aim of this study was to investigate determinants for employer-paid health insurance coverage. Because the policy change affected only people who were part of the labour force and because the public sector at that time had no tradition of providing fringe benefits, the analysis was restricted to the private labour force. The analysis was based on data from a range of Danish person-level and company-level registers (explanatory variables). These data were combined with information on insurance status obtained from the trade organisation for insurance (dependent variable). A logistic regression was performed to estimate the odds of having employer-paid health insurance coverage. The individuals who were most likely to be insured were those employed in foreign companies as mid-level managers within the field of building and construction. Other important variables were the number of persons employed in a company, gender, ethnicity, region of residence, years of education, and annual income. Both company and individual characteristics were found to be important and significant predictors for employer-paid health insurance coverage. The Danish tax exemption on private health insurance in the years 2002-12 thus seems to have led to inequality in employer-paid health insurance coverage.

American Seventh-day Adventists have been reported to have lower cancer mortality and incidence than the general population. Adventists do not consume tobacco, alcohol or pork, and many adhere to a lacto-ovo-vegetarian lifestyle. Baptists discourage excessive use of alcohol and tobacco. In this study, we investigated whether the incidence of cancer in a large cohort of Danish Adventists and Baptists was different compared to the general Danish population. We followed 11,580 Danish Adventists and Baptists in the nationwide Danish Cancer Registry, which contains information on cases of cancer for 1943-2008. Cancer incidence in the cohort was compared with that in the general Danish population as standardized incidence ratios (SIRs) with 95% confidence intervals (CIs), and within-cohort comparisons were made with a Cox model. Lower cancer incidences were observed for both Seventh-day Adventist men (SIR, 66; 95% CI, 60-72) and women (85; 80-91). The same result was observed for Baptists although not as low. The differences were most pronounced for smoking-related cancers such as those of the buccal cavity and lung (SIR, 20; 13-30 for Seventh-day Adventist men and 33; 22-49 for Seventh-day Adventist women). The incidences of other lifestyle-related cancers, such as of stomach, rectum, liver and cervix, were also decreased. In general, the SIRs were lower for men than for women, and Adventists had lower hazard rates than Baptists. Our findings point to the benefits of compliance with public health recommendations and indicate that lifestyle changes in the population might change the cancer risks of individuals.

Psoriasis and asthma are disorders driven by inflammation. Psoriasis may carry an increased risk of asthma, but the reverse relationship has not been investigated. To investigate the risk of psoriasis in subjects with childhood asthma in a nationwide Danish cohort. Data on all Danish individuals aged 6-14 years at study entry between 1 January 1997 and 31 December 2011 (n = 1,478,110) were linked at an individual level in nationwide registers. Incidence rates per 10,000 person-years were calculated, and incidence rate ratios (IRRs) adjusted for age, sex, concomitant medication and comorbidity were estimated by Poisson regression models. There were 21,725 cases of childhood asthma and 6586 incident cases of psoriasis. There were 5697 and 889 incident cases of mild and severe psoriasis, respectively. The incidence rates of overall, mild and severe psoriasis were 4.49, 3.88 and 0.61 for the reference population, and 5.95, 5.18 and 0.83 for subjects with childhood asthma, respectively. The IRRs for overall, mild and severe psoriasis were 3.94 [95% confidence interval (CI) 2.16-7.17], 5.03 (95% CI 2.48-10.21) and 2.27 (95% CI 0.61-8.42) for patients with childhood asthma. Childhood asthma was associated with a significantly increased risk of psoriasis. Further studies are warranted to determine the clinical significance and effects of therapeutic interventions on this association. © 2015 British Association of Dermatologists.

This study examined the extent to which Danish veterinary practices encounter financially limited clients and how different factors relating to the animal, the client and the veterinarian affect decisions to provide treatment for these clients. 300 small animal practices were invited to participate in an online survey. 195 participated, giving a response rate of 65 per cent. The results show that Danish small animal veterinary practices encounter clients with limited finances regularly: 33.8 per cent of them 3-4 times, 24.6 per cent 5-10 times and 19.5 per cent 1-2 times a month. Only around 9 per cent reported having a written practice policy on handling financially limited clients. Factors affecting decisions to treat include the severity and type of the animal's condition, the medical care needed and the client's expressed emotions. The propensity to treat is significantly higher in female veterinarians and in situations involving unborn animals. The overall conclusion is that small animal veterinary practices often provide treatment to clients who are not able to pay-far beyond what is legally required. This can be considered a major economic and psychological challenge for the practising veterinarians. British Veterinary Association.

Objective In a recent study, we found that Greenlandic Inuit children had a more adverse metabolic profile than Danish children. Aerobic fitness and adiposity could only partly account for the differences. Therefore, we set out to evaluate and compare plasma leptin and adiponectin levels in Danish and Inuit children. Methods In total, 187 Inuit and 132 Danish children (5.7–17.1 years) had examinations of anthropometrics, body fat content, pubertal staging, fasting blood and aerobic fitness. Results Plasma leptin was higher in Danish boys [3,774 (4,741–3,005)] [pg/mL unadjusted geometric mean (95% CI)] compared to both northern [2,076 (2,525–1,706)] (p<0.001) and southern (2,515 (3,137–2,016)) (p<0.001) living Inuit boys and higher in Danish girls [6,988 (8,353–5,847)] compared to southern living Inuit girls [4,910 (6,370–3,785)] (p=0.021) and tended to be higher compared to northern living Inuit girls [5,131 (6,444–4,085)] (p=0.052). Plasma adiponectin was higher for both Danish boys [22,359 (2,573–19,428)] [ng/mL unadjusted geometric mean (95% CI)] and girls [26,609 (28,994–24,420)] compared to southern living Inuit boys [15,306 (18,406–12,728)] and girls [18,864 (22,640–15,717)] (both p<0.001), respectively. All differences remained after adjustment for body fat percentage (BF%), aerobic fitness, age and puberty. The leptin/adiponectin ratio was higher in Danish boys and tended to be higher in Danish girls compared to northern living Inuit boys and girls, respectively. These differences were eliminated after adjustment for BF%, aerobic fitness, age and puberty. Conclusions In contrast to our hypothesis, plasma leptin was higher in Danish children despite a more healthy metabolic profile compared to Inuit children. As expected, plasma adiponectin was lowest in Inuit children with the most adverse metabolic profile. PMID:23940841

Plasma leptin was higher in Danish boys [3,774 (4,741-3,005)] [pg/mL unadjusted geometric mean (95% CI)] compared to both northern [2,076 (2,525-1,706)] (p < 0.001) and southern (2,515 (3,137-2,016)) (p < 0.001) living Inuit boys and higher in Danish girls [6,988 (8,353-5,847)] compared to southern living Inuit girls [4,910 (6,370-3,785)] (p = 0.021) and tended to be higher compared to northern living Inuit girls [5,131 (6,444-4,085)] (p = 0.052). Plasma adiponectin was higher for both Danish boys [22,359 (2,573-19,428)] [ng/mL unadjusted geometric mean (95% CI)] and girls [26,609 (28,994-24,420)] compared to southern living Inuit boys [15,306 (18,406-12,728)] and girls [18,864 (22,640-15,717)] (both p < 0.001), respectively. All differences remained after adjustment for body fat percentage (BF%), aerobic fitness, age and puberty. The leptin/adiponectin ratio was higher in Danish boys and tended to be higher in Danish girls compared to northern living Inuit boys and girls, respectively. These differences were eliminated after adjustment for BF%, aerobic fitness, age and puberty. In contrast to our hypothesis, plasma leptin was higher in Danish children despite a more healthy metabolic profile compared to Inuit children. As expected, plasma adiponectin was lowest in Inuit children with the most adverse metabolic profile.

The aim of the study is to compare differences in cancer stage at diagnosis between migrant women and native Danish women. The stage is used as a clinical indicator of access to healthcare until the point of diagnosis. Refugees and family reunited migrants who received residence permits in Denmark from 1 January 1993 to 31 December 1999 were included and matched 1 : 4 on age and sex with a Danish-born reference population. Our final female population included 24 734 migrants and 123 670 controls. Civil registration numbers of the cohort were linked to the Danish Cancer Registry whereby cases were identified in the period 1.1.1993-31.12.2002. Only women from Eastern Europe and the Middle East were included. This amounted to 269 migrants and 1608 native Danes. Data from the Danish Cancer Registry included diagnosis, time of diagnosis and disease stage at diagnosis. Our initial analyses of migrant subgroups showed that migrant women had decreased odds ratios of being diagnosed at the local stage and increased odds of having unknown stage, although these tendencies were mainly not statistically significant. A subsequent analysis of an overall migrant effect on all cancer sites emphasized these tendencies. This analysis reached borderline significance for local versus nonlocal stage and significance for unknown versus known stage. Our results indicate that migrant women may experience barriers in access to healthcare until cancer diagnosis compared with Danish women. More research is, however, needed to confirm our results and to find out if they indicate general problems concerning migrants' access to healthcare in Denmark.

Patients ≥18 years operated for groin hernia. Type and size of hernia, primary or recurrent, type of surgical repair procedure, mesh and mesh fixation methods. According to the Danish National Health Act, surgeons are obliged to register all hernia repairs immediately after surgery (3 minute registration time). All institutions have continuous access to their own data stratified on individual surgeons. Registrations are based on a closed, protected Internet system requiring personal codes also identifying the operating institution. A national steering committee consisting of 13 voluntary and dedicated surgeons, 11 of whom are unpaid, handles the medical management of the database. The Danish Inguinal Hernia Database comprises intraoperative data from >130,000 repairs (May 2015). A total of 49 peer-reviewed national and international publications have been published from the database (June 2015).

Background Opioids may alter immune function and thereby potentially affect cancer recurrence. We investigated the association between post-diagnosis opioid use and breast cancer recurrence. Methods We identified incident early-stage breast cancer patients, diagnosed 1996-2008 in Denmark, registered in the Danish Breast Cancer Cooperative Group Registry. Opioid prescriptions were ascertained from the Danish National Prescription Registry. Follow-up began on the date of breast cancer primary surgery and continued until breast cancer recurrence, death, emigration, ten years, or 31 July 2013, whichever occurred first. We used Cox regression models to compute hazard ratios (HRs) and 95% confidence intervals (95%CI) associating breast cancer recurrence with opioid prescription use overall, and by opioid type and strength, immunosuppressive effect, chronic use (>=6 months continuous exposure), and cumulative morphine-equivalent dose, adjusting for confounders. Results We identified 34,188 patients who together contributed 283,666 person-years of follow-up. There was no association between ever use of opioids and breast cancer recurrence (HRcrude=0.98, 95% CI=0.90 - 1.1, and HRadjusted=1.0, 95% CI=0.92 - 1.1), regardless of opioid type, strength, chronicity of use, and cumulative dose. Breast cancer recurrence rates were lower among users of strong but not weakly immunosuppressive opioids, possibly due to channeling bias among those with high competing risk as mortality was higher among users of this drug type. Conclusions This large prospective cohort study provided no clinically relevant evidence of an association between opioid prescriptions and breast cancer recurrence. Our findings are important to cancer survivorship, as opioids are frequently used to manage pain associated with comorbid conditions. PMID:26207518

Assessment of heterogeneity between European Populations: a Baltic and Danish replication case-control study of SNPs from a recent European ulcerative colitis genome wide association study

PubMed Central

2011-01-01

Background Differences in the genetic architecture of inflammatory bowel disease between different European countries and ethnicities have previously been reported. In the present study, we wanted to assess the role of 11 newly identified UC risk variants, derived from a recent European UC genome wide association study (GWAS) (Franke et al., 2010), for 1) association with UC in the Nordic countries, 2) for population heterogeneity between the Nordic countries and the rest of Europe, and, 3) eventually, to drive some of the previous findings towards overall genome-wide significance. Methods Eleven SNPs were replicated in a Danish sample consisting of 560 UC patients and 796 controls and nine missing SNPs of the German GWAS study were successfully genotyped in the Baltic sample comprising 441 UC cases and 1156 controls. The independent replication data was then jointly analysed with the original data and systematic comparisons of the findings between ethnicities were made. Pearson's χ2, Breslow-Day (BD) and Cochran-Mantel-Haenszel (CMH) tests were used for association analyses and heterogeneity testing. Results The rs5771069 (IL17REL) SNP was not associated with UC in the Danish panel. The rs5771069 (IL17REL) SNP was significantly associated with UC in the combined Baltic, Danish and Norwegian UC study sample driven by the Norwegian panel (OR = 0.89, 95% CI: 0.79-0.98, P = 0.02). No association was found between rs7809799 (SMURF1/KPNA7) and UC (OR = 1.20, 95% CI: 0.95-1.52, P = 0.10) or between UC and all other remaining SNPs. We had 94% chance of detecting an association for rs7809799 (SMURF1/KPNA7) in the combined replication sample, whereas the power were 55% or lower for the remaining SNPs. Statistically significant PBD was found for OR heterogeneity between the combined Baltic, Danish, and Norwegian panel versus the combined German, British, Belgian, and Greek panel (rs7520292 (P = 0.001), rs12518307 (P = 0.007), and rs2395609 (TCP11) (P = 0.01), respectively

Surveillance of maritime deaths on board Danish merchant ships, 1986-2009.

A previous study demonstrated a high death rate among seafarers signed on Danish ships during the years 1986-1993. This study aimed to examine and analyse the subsequent development until 2009. A total of 356 fatalities were identified from data supplied from the Danish Maritime Authority, an insurance company, and other sources. Maritime deaths among seafarers signed on Danish ships comprise deaths from 1) accidents, suicides and homicides; and 2) disease on board. Deaths due to 2) occurring ashore within 30 days after signing off were included. The overall and mode-specific death rates were calculated for three eight-year observation periods. The rates for work-related fatal accidents were compared with the rates for land-based trades. All categories of maritime deaths were significantly reduced from 1986 to 2009 - in particular during the last eight-year period (Accidents 1986-1993: 66.6 per 100,000 person years, 2002-2009: 27.0 per 100,000 person years, diseases 49.5-26.1, suicides 14.4-7.8). In spite of the remarkable improvement since 1986, seafarers remain in 2002-2009 more than six times more likely to die from occupational accidents (including shipwrecks) than do workers ashore. The favourable trend of maritime deaths in the Danish merchant fleet may be due to 1) preventive measures - e.g. interventions relating to vessel safety, work environment, and improved medical care on board - and to 2) technological and organizational changes - e.g. newer and larger vessels in the Danish merchant fleet, changed composition of the workforce, and reduced shore leaves. The persisting excess risk warrants further preventive actions.

Barriers among Danish women and general practitioners to raising the issue of intimate partner violence in general practice: a qualitative study

PubMed Central

2014-01-01

Background Thirty-five percent of Danish women experience sexual or physical violence in their lifetime. However, health care professionals are not in the practice of asking about intimate partner violence (IPV) in Denmark. It is currently unknown what hinders general practitioners from asking about partner violence and how Danish women would perceive such an inquiry. This aspect has not previously been explored in Denmark. An exploratory study was conducted to examine what hinders general practitioners (GPs) from asking and what Danish women’s views and attitudes are regarding being asked about IPV. Methods Data were collected through individual and group interviews with a sample of three GPs and a diverse sample of 13 women, including both survivors of partner violence and those without any history of partner violence. An interpretative analysis was performed with the data. Results This study provides important knowledge regarding the barriers and attitudes towards inquiry about IPV in primary care in Denmark. Results indicate that Denmark is facing the same challenges when responding to survivors of IPV as other similar countries, including Sweden, Norway, the UK, USA, and Australia. Danish women want general practitioners to ask about violence in a respectful and non-judgemental manner. However, general practitioners are resistant towards such an inquiry and would benefit from training regarding how to respond to women who have been exposed to IPV. Conclusions It is acceptable to inquire about IPV with women in Denmark in a non-judgemental and respectful way. Informing about IPV prevalence is important prior to the inquiry. However, general practitioners require more awareness and training before a favourable environment for this change in procedure can be created. Further large-scale research is needed to support the evidence generated by this small study. PMID:24893567

Small reference populations limit the accuracy of genomic prediction in numerically small breeds, such like Danish Jersey. The objective of this study was to investigate two approaches to improve genomic prediction by increasing size of reference population in Danish Jersey. The first approach was to include North American Jersey bulls in Danish Jersey reference population. The second was to genotype cows and use them as reference animals. The validation of genomic prediction was carried out on bulls and cows, respectively. In validation on bulls, about 300 Danish bulls (depending on traits) born in 2005 and later were used as validation data, and the reference populations were: (1) about 1050 Danish bulls, (2) about 1050 Danish bulls and about 1150 US bulls. In validation on cows, about 3000 Danish cows from 87 young half-sib families were used as validation data, and the reference populations were: (1) about 1250 Danish bulls, (2) about 1250 Danish bulls and about 1150 US bulls, (3) about 1250 Danish bulls and about 4800 cows, (4) about 1250 Danish bulls, 1150 US bulls and 4800 Danish cows. Genomic best linear unbiased prediction model was used to predict breeding values. De-regressed proofs were used as response variables. In the validation on bulls for eight traits, the joint DK-US bull reference population led to higher reliability of genomic prediction than the DK bull reference population for six traits, but not for fertility and longevity. Averaged over the eight traits, the gain was 3 percentage points. In the validation on cows for six traits (fertility and longevity were not available), the gain from inclusion of US bull in reference population was 6.6 percentage points in average over the six traits, and the gain from inclusion of cows was 8.2 percentage points. However, the gains from cows and US bulls were not accumulative. The total gain of including both US bulls and Danish cows was 10.5 percentage points. The results indicate that sharing reference

Little is known about the physical and psychosocial work environment of chiropractors and their work-related health complaints, and this has never been described for Danish chiropractors. The aim of this study was, therefore, to describe work-related acute physical injuries, overuse complaints, and psychosocial stress in Danish chiropractic work settings. We developed a questionnaire specifically for this study and distributed it electronically in August 2016 using SurveyXact to all 575 members of the Danish Chiropractors' Association working in primary care clinics. Chiropractors were asked about their work-related acute physical injuries and overuse complaints as well as any psychosocial stress they experienced at work during the previous year. We described our sample and variables using means, medians, ranges, and confidence intervals where appropriate. Statistically significant differences between genders, types of complaints and injuries, and between clinic owners and associates were examined using Chi-square and Fischer's exact tests, where appropriate, or by examining confidence intervals for non-overlap. 355 (65.2%) chiropractors answered the survey. Of these, 216 (61%, 95% CI 56-66) had experienced a work-related acute physical injury and/or overuse complaint during the previous year. Work-related overuse complaints were most commonly reported in the low back, wrist, thumb, and shoulder, and were more common among women (63%, 95% CI 56-70) than men (51%, 95% CI 43-59). Chiropractors with more than five years in practice (59%, 95% CI 52-64) reported significantly fewer work-related acute injuries and overuse complaints during the previous year compared with chiropractors with less than five years in practice (83%, 95% CI 73-91). In general, these practicing Danish chiropractors reported having a good psychosocial work environment, and 90% of chiropractors "always" or "often" felt that they were motivated and committed to their work.

Dietary studies show a relationship between the intake of iron enhancers and inhibitors and iron stores in the general population. However, the impact of dietary factors on the iron stores of blood donors, whose iron status is affected by blood donations, is incompletely understood. In the Danish Blood Donor Study, we assessed the effect of blood donation frequency, physiologic factors, lifestyle and supplemental factors, and dietary factors on ferritin levels. We used multiple linear and logistic regression analyses stratified by sex and menopausal status. Among high-frequency donors (more than nine donations in the past 3 years), we found iron deficiency (ferritin below 15 ng/mL) in 9, 39, and 22% of men, premenopausal women, and postmenopausal women, respectively. The strongest predictors of iron deficiency were sex, menopausal status, the number of blood donations in a 3-year period, and the time since last donation. Other significant factors included weight, age, intensity of menstruation, iron tablets, vitamin pills, and consumption of meat and wine. The study confirms iron deficiency as an important problem, especially among menstruating women donating frequently. The risk of iron depletion was largely explained by sex, menopausal status, and donation frequency. Other factors, including dietary and supplemental iron intake, had a much weaker effect on the risk of iron depletion. © 2013 The Authors.

Review of four publications on the Danish cohort study on mobile phone subscribers and risk of brain tumors.

2012-01-01

Since the International Agency for Research on Cancer recently classified radiofrequency electromagnetic fields, such as those emanating from mobile and cordless phones, as possibly carcinogenic to humans (group 2B), two additional reports relevant to the topic have been published. Both articles were new updates of a Danish cohort on mobile phone subscribers and concern the possible association between assumed use of mobile phones and risk of brain tumors. The aim of the present review is to reexamine all four publications on this cohort. In brief, publications were scrutinized, and in particular, if the authors made explicit claims to have either proved or disproved their hypothesis, such claims were reviewed in light of applied methods and study design, and in principle, the stronger the claims, the more careful our review. The nationwide Danish cohort study on mobile phone subscribers and risk of brain tumors, including at best 420,095 persons (58% of the initial cohort), is the only one of its kind. In comparison with previous investigations, i.e., case-control studies, its strength lies in the possibility to eliminate non-response, selection, and recall bias. Although at least non-response and recall bias can be excluded, the study has serious limitations related to exposure assessment. In fact, these limitations cloud the findings of the four reports to such an extent that render them uninformative at best. At worst, they may be used in a seemingly solid argument against an increased risk--as reassuring results from a large nationwide cohort study, which rules out not only non-response and recall bias but also an increased risk as indicated by tight confidence intervals. Although two of the most comprehensive case-control studies on the matter both have methodological limitations that need to be carefully considered, type I errors are not the only threats to the validity of studies on this topic--the Danish cohort study is a textbook example of that.

Since information about macro- and micronutrient intake among vegans is limited we aimed to determine and evaluate their dietary and supplementary intake. Seventy 18-61 years old Danish vegans completed a four-day weighed food record from which their daily intake of macro- and micronutrients was assessed and subsequently compared to an age-range-matched group of 1,257 omnivorous individuals from the general Danish population. Moreover, the vegan dietary and supplementary intake was compared to the 2012 Nordic Nutrition Recommendations (NNR). Dietary intake differed significantly between vegans and the general Danish population in all measured macro- and micronutrients (p < 0.05), except for energy intake among women and intake of carbohydrates among men. For vegans the intake of macro- and micronutrients (including supplements) did not reach the NNR for protein, vitamin D, iodine and selenium. Among vegan women vitamin A intake also failed to reach the recommendations. With reference to the NNR, the dietary content of added sugar, sodium and fatty acids, including the ratio of PUFA to SFA, was more favorable among vegans. At the macronutrient level, the diet of Danish vegans is in better accordance with the NNR than the diet of the general Danish population. At the micronutrient level, considering both diet and supplements, the vegan diet falls short in certain nutrients, suggesting a need for greater attention toward ensuring recommended daily intake of specific vitamins and minerals.

Assessment of the probability of introducing Mycobacterium tuberculosis into Danish cattle herds.

Tuberculosis is a zoonosis caused by Mycobacterium spp. International trade in cattle is regulated with respect to Mycobacterium bovis (M. bovis) but not Mycobacterium tuberculosis (M. tuberculosis), despite that cattle can become infected with both species. In this study we estimated the annual probability (PIntro) of introducing M. tuberculosis into the Danish cattle population, by the import of cattle and/or by immigrants working in Danish cattle herds. Data from 2013 with date, number, and origin of imported live cattle were obtained from the Danish cattle database. Information on immigrants working in Danish cattle herds was obtained through a questionnaire sent to Danish cattle farmers. The gained inputs were fed into three stochastic scenario trees to assess the PIntro for the current and alternative test-and-manage strategies, such as testing of imported animals and/or testing immigrant workers with the tuberculin skin test. We considered the population of Danish farmers and practitioners free of tuberculosis, because in Denmark, the incidence of the disease in humans is low and primarily related to immigrants and socially disadvantaged people. The median annual probability of introducing M. tuberculosis into the Danish cattle population due to imported live cattle was 0.008% (90% P.I.: 0.0007%; 0.03%), while the probability due to immigrant workers was 4.1% (90% P.I.: 0.8%; 12.1%). The median combined probability (PIntro) due to imported cattle plus workers was 4.1% (90% P.I.: 0.8%; 12.6%). Hence, on average at least one introduction each 24 (90% P.I.: 8; 125) years could be expected. Imported live cattle appeared to play a marginal role on the overall annual PIntro, because they represented only approximately 0.2% of the median annual probability. By testing immigrant workers the overall annual PIntro could be reduced to 0.2% (90% P.I.: 0.04%; 0.7%). Thus, testing of immigrant workers could be considered as a risk mitigation strategy to markedly reduce

The Danish Neuro-Oncology Registry (DNOR) is a nationwide clinical cancer database that has prospectively registered data on patients with gliomas since January 2009. The purpose of this study was to describe the establishment of the DNOR and further to evaluate the database completeness of patient registration and validity of data. The completeness of the number of patients registered in the database was evaluated in the study period from January 2009 through December 2014 by comparing cases reported to the DNOR with the Danish National Patient Registry and the Danish Pathology Registry. The data validity of important clinical variables was evaluated by a random sample of 100 patients from the DNOR using the medical records as reference. A total of 2241 patients were registered in the DNOR by December 2014 with an overall patient completeness of 92 %, which increased during the study period (from 78 % in 2009 to 96 % in 2014). Medical records were available for all patients in the validity analyses. Most variables showed a high agreement proportion (56-100 %), with a fair to good chance-corrected agreement (k = 0.43-1.0). The completeness of patient registration was very high (92 %) and the validity of the most important patient data was good. The DNOR is a newly established national database, which is a reliable source for future scientific studies and clinical quality assessments among patients with gliomas.

Prehospital resuscitation is often challenging. Giving uninterrupted and effective compressions is relatively impossible during transportation. In 2012, The Royal Danish Air Force received a donation of 8 mechanical chest compression devices (LUCAS(™)2; Physio-Control/Jolife AB, Lund, Sweden) to be used onboard the Danish search and rescue (SAR) helicopters. The scope of this investigation was to establish whether or not mechanical chest compression devices should be considered a necessity onboard the Danish SAR helicopters. Data were compiled from SAR medical journals. From the data collected, observations were made as to when LUCAS(™)2 was used and what diagnosis the SAR physician made. One thousand ninety missions were registered in the 24-month research period, and LUCAS(™)2 was used in 25 missions. Cardiac emergencies amounted for 25% of the missions. The Danish SAR helicopters retrieved 33 drowned/hypothermic patients during the research period, and the LUCAS(™)2 was used in 11 of the patients requiring resuscitation. The LUCAS(™)2 was frequently used during other emergencies like sudden cardiac arrest. Cardiac emergencies were the predominant type of mission. LUCAS(™)2 is now considered mandatory on Danish SAR helicopters. Copyright © 2016 Air Medical Journal Associates. Published by Elsevier Inc. All rights reserved.

Investigating the use of mental health services by combat veterans can help illuminate utilization and unmet needs of this population. The aims of this study were to estimate the use of mental health services and to examine how such use is associated with self-reported symptoms of posttraumatic stress disorder (PTSD) in soldiers before and after deployment to Afghanistan. Prospectively, 703 Danish soldiers who deployed from January 2009 to August 2009 were followed up with 6 assessments from predeployment to 2.5 years postdeployment in 2012. At assessments, the soldiers responded to a comprehensive questionnaire including a measure of PTSD symptoms (the PTSD Checklist-Civilian version). These self-reported data were combined with individual-level records of receiving psychotherapy from the Military Psychological Division at the Danish Defense and psychiatric treatment from the Danish registers. The prevalence of PTSD symptoms increased over time, and almost 10% of the sample reported high levels of PTSD symptoms 2.5 years postdeployment. Overall, 37% of the soldiers utilized mental health services; 6% utilized psychiatric services, and 12.4% redeemed a prescription for psychiatric medicine. Approximately one-third received psychotherapy at the Military Psychological Division. In those reporting high PTSD symptomatology, 83% utilized 1 or more types of mental health service. At predeployment and homecoming, high PTSD symptomatology was significantly (P < .01) associated with attending psychotherapy, but not with psychiatric treatment or redemption of psychiatric medicine. With time, more soldiers report high PTSD symptoms. Among Danish soldiers with high symptomatology, the utilization of mental health services was high. Most frequently, soldiers with high PTSD symptomatology received psychotherapy at the Military Psychological Division and less frequently received psychiatric treatment. © Copyright 2016 Physicians Postgraduate Press, Inc.

This study compares the number of criminal charges among problem gamblers (N = 384) and non-problem gamblers including non-gamblers (N = 18,241) and examines whether problem gambling is more strongly associated with income-generating crimes like theft, fraud and forgery than other types of crimes such as violent crimes. A cohort study was carried out, based on data from the Danish Health and Morbidity Surveys in 2005 and 2010, which were linked at the individual level with data from The Danish National Criminal Register. Multiple logistic regression analyses were used to determine the association between problem gambling and charges for different categories of crime. We found that problem gamblers had significantly higher odds of being charged than non-problem gamblers (adjusted odds ratio 1.5; 95 % confidence interval 1.1-1.9). The odds ratio for economic crime charges was 2.6 (1.5-4.5), for violence charges 2.2 (1.1-4.5), and for drug charges 3.7 (1.7-8.0). For road traffic charges the odds ratio was 1.3 (1.0-1.8). Hence, there was a strong association between problem gambling and being charged except for road traffic charges; however the association was not stronger for economic charges than for violence and drug charges.

School food in many countries has become the object of change and innovation processes, not only in relation to policies for healthier eating but also in relation to policies for more sustainable food consumption and procurement. The purpose of this study was to examine the possible influence that organic food sourcing policies in Danish school meal systems may have on the development of healthier school food environments. The study was a cross-sectional analysis undertaken among 179 school food coordinators (SFCs) through a web-based questionnaire (WBQ) in a sample of Danish public primary schools. The 'organic' schools were compared to 'non-organic' schools. The questionnaire explored the attitudes, intentions/policies and actions in relation to organic and healthy foods served in the schools. Data indicates that 20 'organic' schools were associated with the indicators of healthier school environments, including adopting a Food and Nutrition Policy (FNP) in the school (p = .032), recommending children to eat healthily (p = .004). The study suggests that organic food policies in schools may have potential to support a healthier school food environment.

To examine the effects of fertility drugs on overall risk of ovarian cancer using data from a large cohort of infertile women. Population based cohort study. Danish hospitals and private fertility clinics. 54,362 women with infertility problems referred to all Danish fertility clinics during 1963-98. The median age at first evaluation of infertility was 30 years (range 16-55 years), and the median age at the end of follow-up was 47 (range 18-81) years. Included in the analysis were 156 women with invasive epithelial ovarian cancer (cases) and 1241 subcohort members identified in the cohort during follow-up in 2006. Effect of four groups of fertility drugs (gonadotrophins, clomifene citrate, human chorionic gonadotrophin, and gonadotrophin releasing hormone) on overall risk of ovarian cancer after adjustment for potential confounding factors. Analyses within cohort showed no overall increased risk of ovarian cancer after any use of gonadotrophins (rate ratio 0.83, 95% confidence interval 0.50 to 1.37), clomifene (1.14, 0.79 to 1.64), human chorionic gonadotrophin (0.89, 0.62 to 1.29), or gonadotrophin releasing hormone (0.80, 0.42 to 1.51). Furthermore, no associations were found between all four groups of fertility drugs and number of cycles of use, length of follow-up, or parity. No convincing association was found between use of fertility drugs and risk of ovarian cancer.

Intelligence is a life-long trait that has strong influences on lifestyle, adult morbidity and life expectancy. Hence, lower cognitive abilities are therefore of public health interest. Our primary aim was to examine if prenatal bereavement measured as exposure to death of a close family member is associated with the intelligence quotient (IQ) scores at 18-years of age of adult Danish males completing a military cognitive screening examination. We extracted records for the Danish military screening test and found kinship links with biological parents, siblings, and maternal grandparents using the Danish Civil Registration System (N = 167,900). The prenatal exposure period was defined as 12 months before conception until birth of the child. We categorized children as exposed in utero to severe stress (bereavement) during prenatal life if their mothers lost an elder child, husband, parent or sibling during the prenatal period; the remaining children were included in the unexposed cohort. Mean score estimates were adjusted for maternal and paternal age at birth, residence, income, maternal education, gestational age at birth and birth weight. When exposure was due to death of a father the offsprings' mean IQ scores were lower among men completing the military recruitment exam compared to their unexposed counterparts, adjusted difference of 6.5 standard IQ points (p-value = 0.01). We did not observe a clinically significant association between exposure to prenatal maternal bereavement caused by death of a sibling, maternal uncle/aunt or maternal grandparent even after stratifying deaths only due to traumatic events. We found maternal bereavement to be adversely associated with IQ in male offspring, which could be related to prenatal stress exposure though more likely is due to changes in family conditions after death of the father. This finding supports other literature on maternal adversity during fetal life and cognitive development in the offspring.

To examine labour market participation and long-term sick leave following a diagnosis with myasthenia gravis (MG) compared with the general Danish population and for specific subgroups of MG patients. A nationwide matched cohort study from 1997 to 2011 using data from population-based medical and social registries. The study includes 330 MG patients aged 18 to 65 years old identified from hospital diagnoses and dispensed prescriptions, and twenty references from the Danish population matching each MG patient on age, gender, and profession. Main outcome measures are labour market participation (yes/no) and long-term sick leave ≥9 weeks (yes/no) with follow-up at 1- and 2 years after the time of MG diagnosis or match. Based on complete person-level information on all public transfer payments in Denmark, persons having no labour market participation are defined as individuals receiving social benefits for severely reduced workability, flexijob, and disability pension. MG is consistently associated with higher odds of having no labour market participation and long-term sick leave compared with the general Danish population (no labour market participation & ≥9 weeks sick leave at 2-year follow-up, adjusted OR (95% CI): 5.76 (4.13 to 8.04) & 8.60 (6.60 to 11.23)). Among MG patients, females and patients treated with both acetylcholinesterase inhibitors and immunosuppression have higher odds of lost labour market participation and long-term sick leave. This study suggests that MG patients have almost 6 times higher odds of no labour market participation and almost 9 times higher odds of long-term sick leave 2 years after diagnosis compared with the general Danish population. In particular female MG patients and patients treated with both acetylcholinesterase and immunosuppression have high odds of a negative labour market outcome. Future research should focus on predictors in workplace and labour market policy of labour market participation among MG patients.

Negative body perception has been reported in a number of patient populations. No instrument in Danish for measuring body image-related concerns has been available. Without such an instrument, understanding of the phenomenon in Danish-speaking populations is limited. The purpose of the study was thus to translate and validate a Danish version of the Body Image Quality of Life Inventory (BIQLI), in order to obtain a valid instrument applicable for healthcare research. The study consisted of two phases: (i) instrument adaptation, including forward and back translation, expert committee comparisons and cognitive interviewing, and (ii) empirical testing of the Danish version (BIQLI-DA) with subsequent psychometric evaluation. Hypothesised correlations to other measures, including body mass index (BMI), Medical Outcome Short Form-8 (SF-8), Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder-7 and Symptom Check List-90-Revised (SCL-90-R ® ) were tested. In addition, exploratory factor structure analysis (EFA) and internal consistency on item and scale level were performed. The adapted instrument was found to be semantically sound, yet concerns about face validity did arise through cognitive interviews. Danish college students (n = 189, 65 men, M age = 21.1 years) participated in the piloting of the BIQLI-DA. Convergent construct validity was demonstrated through associations to related constructs. Exploratory factor analysis revealed a potential subscale structure. Finally, results showed a high internal consistency (Cronbach's alpha = 0.92). Support for the validity of the BIQLI-DA might have been strengthened by repeating cognitive interviews after layout alterations, by piloting the instrument on a larger sample. This study demonstrated tentative support for the validity of the Danish Body Image Quality of Life (BIQLI-DA) and found the measure to be reliable in terms of internal consistency.

The objective of this study was to assess the genetic variability of the detailed fatty acid (FA) profiles of Danish Holstein (DH) and Danish Jersey (DJ) cattle populations. We estimated genetic parameters for 11 FA or groups of FA in milk samples from the Danish milk control system between May 2015 and October 2016. Concentrations of different FA and FA groups in milk samples were measured by mid-infrared spectroscopy. Data used for parameter estimation were from 132,732 first-parity DH cows and 21,966 first-parity DJ cows. We found the highest heritabilities for test day measurements in both populations for short-chain FA (DH = 0.16; DJ = 0.16) and C16:0 (DH = 0.14; DJ = 0.16). In DH, the highest heritabilities were also found for saturated FA and monounsaturated FA (both populations: 0.15). Genetic correlations between the fatty acid traits showed large differences between DH and DJ for especially short-chain FA with the other FA traits measured. Furthermore, genetic correlations of total fat with monounsaturated FA, polyunsaturated FA, short-chain FA, and C16:0 differed markedly between DH and DJ populations. In conclusion, we found genetic variation in the mid-infrared spectroscopy-predicted FA and FA groups of the DH and DJ cattle populations. This finding opens the possibility of using genetic selection to change the FA profiles of dairy cattle. The Authors.

2013-01-01

Thyroid hormones are essential for brain development, and maternal thyroid disease may affect child neurocognitive development. Some types of seizures may also depend upon early exposure of the developing central nervous system, and we hypothesized that maternal thyroid dysfunction could increase the risk of seizure in the child. In a Danish population-based study we included 1,699,693 liveborn singletons, and from the Danish National Hospital Register we obtained information on maternal diagnosis of hyper- or hypothyroidism and neonatal seizure, febrile seizure, and epilepsy in the child. Maternal diagnosis of thyroid dysfunction before or after birth of the child was registered in two percent of the singleton births. In adjusted analyses, maternal hyperthyroidism and hypothyroidism first time diagnosed after birth of the child were associated with a significant increased risk of epilepsy in the child. Moreover, hypothyroidism diagnosed after birth of the child was associated with a significant increased risk of neonatal and febrile seizures. No significant association was seen for maternal diagnosis prior to birth of the child. We speculate if some degree of maternal thyroid dysfunction was already present during the pregnancy in mothers diagnosed after birth of the child and if this untreated condition may present a neurodevelopmental risk.

This article aims to describe and assess the Danish case-mix system, the cost accounting applied in setting national tariffs and the introduction of variable, prospective payment in the Danish hospital sector. The tariffs are calculated as a national average from hospital data gathered in a national cost database. However, uncertainty, mainly resulting from the definition of cost centres at the individual hospital, implies that the cost weights may not fully reflect the hospital treatment cost. As variable prospective payment of hospitals currently only applies to 20% of a hospital's budget, the incentives and the effects on productivity, quality and equality are still limited.

Although increased risk for schizophrenia among immigrants is well established, knowledge of the broader spectrum of psychiatric disorders associated with a foreign migration background is lacking. To examine the full range of psychiatric disorders associated with any type of foreign migration background among persons residing in Denmark, including foreign-born adoptees, first- and second-generation immigrants, native Danes with a history of foreign residence, and persons born abroad to Danish expatriates. Danish population-based cohort study. Persons were followed up from their 10th birthday for the development of mental disorders based on outpatient and inpatient data. All persons born between January 1, 1971, and December 31, 2000 (N = 1 859 419) residing in Denmark by their 10th birthday with follow-up data to December 31, 2010. Incidence rate ratios (IRRs) and cumulative incidences for psychiatric outcomes. All categories of foreign migration background, except persons born abroad to Danish expatriates, were associated with increased risk for at least 1 psychiatric disorder. Foreign-born adoptees had increased IRRs for all psychiatric disorders and had the highest IRRs for these disorders compared with other foreign migration categories. First- and second-generation immigrants having 2 foreign-born parents had significantly increased IRRs for schizophrenia and schizophrenia spectrum disorders and had similar risk magnitudes. Second-generation immigrants having 1 foreign-born parent had significantly increased IRRs for all psychiatric disorders. Native Danes with a history of foreign residence had increased IRRs for bipolar affective disorder, affective disorders, personality disorders, and schizophrenia spectrum disorders. The extent to which a background of foreign migration confers an increased risk for the broad spectrum of psychiatric disorders varies according to parental origin, with greatest risks for foreign-born adoptees.

Inappropriate use of antibiotics is contributing to the increasing rates of antimicrobial resistance. Several Danish guidelines on antibiotic prescribing for acute respiratory tract infections in general practice have been issued to promote rational prescribing of antibiotics, however it is unclear if these recommendations are followed. We aimed to characterise the pattern of antibiotic prescriptions for patients diagnosed with acute respiratory tract infections, by means of electronic prescriptions, labeled with clinical indications, from Danish general practice. Acute respiratory tract infections accounted for 456,532 antibiotic prescriptions issued between July 2012 and June 2013. Pneumonia was the most common indication with 178,354 prescriptions (39%), followed by acute tonsillitis (21%) and acute otitis media (19%). In total, penicillin V accounted for 58% of all prescriptions, followed by macrolides (18%) and amoxicillin (15%). The use of second-line agents increased with age for all indications, and comprised more than 40% of the prescriptions in patients aged >75 years. Women were more often prescribed antibiotics regardless of clinical indication. This is the first Danish study to characterise antibiotic prescription patterns for acute respiratory tract infections by data linkage of clinical indications. The findings confirm that penicillin V is the most commonly prescribed antibiotic agent for treatment of patients with an acute respiratory tract infection in Danish general practice. However, second-line agents like macrolides and amoxicillin with or without clavulanic acid are overused. Strategies to improve the quality of antibiotic prescribing especially for pneumonia, acute otitis media and acute rhinosinusitis are warranted. TRACKING THE OVERUSE OF ANTIBIOTICS: Better adherence to guidelines for prescribing antibiotics for different respiratory tract infections are warranted in Danish general practice.

Background Accumulating evidence suggests that statins affect diseases other than cardiovascular disease, including cancer, and that these effects may depend on the lipid solubility of specific statins. Though many studies have reported an association between statin use and breast cancer incidence, the relationship between statin use and breast cancer recurrence has not been well studied. Methods We conducted a nationwide, population-based prospective cohort study of all female residents in Denmark diagnosed with stage I–III invasive breast carcinoma who were reported to the Danish Breast Cancer Cooperative Group registry between 1996 and 2003 (n = 18 769). Women were followed for a median of 6.8 years after diagnosis. Prescriptions for lipophilic and hydrophilic statins were ascertained from the national electronic pharmacy database. Associations between statin prescriptions and breast cancer recurrence were estimated with generalized linear models and Cox proportional hazards regression with adjustment for age and menopausal status at diagnosis; histological grade; estrogen receptor status; receipt of adjuvant therapy; type of primary surgery received; pre-diagnosis hormone replacement therapy; and co-prescriptions of aspirin, angiotensin-converting enzyme inhibitors, nonsteroidal anti-inflammatory drugs, or anticoagulants. All statistical tests were two-sided. Results Most prescriptions for lipophilic statins in the study population were for simvastatin. Exclusive simvastatin users experienced approximately 10 fewer breast cancer recurrences per 100 women after 10 years of follow-up (adjusted 10-year risk difference = −0.10, 95% confidence interval = −0.11 to −0.08), compared with women who were not prescribed a statin. Exclusive hydrophilic statin users had approximately the same risk of breast cancer recurrence as women not prescribed a statin over follow-up (adjusted 10-year risk difference = 0.05, 95% confidence interval = −0.01 to 0

The acceptable noise level (ANL) test is used for quantification of the amount of background noise subjects accept when listening to speech. This study investigates Danish hearing-aid users' ANL performance using Danish and non-semantic speech signals, the repeatability of ANL, and the association between ANL and outcome of the international outcome inventory for hearing aids (IOI-HA). ANL was measured in three conditions in both ears at two test sessions. Subjects completed the IOI-HA and the ANL questionnaire. Sixty-three Danish hearing-aid users; fifty-seven subjects were full time users and 6 were part time/non users of hearing aids according to the ANL questionnaire. ANLs were similar to results with American English speech material. The coefficient of repeatability (CR) was 6.5-8.8 dB. IOI-HA scores were not associated to ANL. Danish and non-semantic ANL versions yield results similar to the American English version. The magnitude of the CR indicates that ANL with Danish and non-semantic speech materials is not suitable for prediction of individual patterns of future hearing-aid use or evaluation of individual benefit from hearing-aid features. The ANL with Danish and non-semantic speech materials is not related to IOI-HA outcome.

With political support from the Danish Organic Action Plan 2020, organic public procurement in Denmark is expected to increase. In order to evaluate changes in organic food procurement in Danish public kitchens, reliable methods are needed. The present study aimed to compare organic food procurement measurements by two methods and to collect and discuss baseline organic food procurement measurements from public kitchens participating in the Danish Organic Action Plan 2020. Comparison study measuring organic food procurement by applying two different methods, one based on the use of procurement invoices (the Organic Cuisine Label method) and the other on self-reported procurement (the Dogme method). Baseline organic food procurement status was based on organic food procurement measurements and background information from public kitchens. Public kitchens participating in the six organic food conversion projects funded by the Danish Organic Action Plan 2020 during 2012 and 2013. Twenty-six public kitchens (comparison study) and 345 public kitchens (baseline organic food procurement status). A high significant correlation coefficient was found between the two organic food procurement measurement methods (r=0·83, P<0·001) with measurements relevant for the baseline status. Mean baseline organic food procurement was found to be 24 % when including measurements from both methods. The results indicate that organic food procurement measurements by both methods were valid for the baseline status report of the Danish Organic Action Plan 2020. Baseline results in Danish public kitchens suggest there is room for more organic as well as sustainable public procurement in Denmark.

International studies have shown blood lead at levels causing health concern in recreational indoor shooters. We hypothesized that Danish recreational indoor shooters would also have a high level of blood lead, and that this could be explained by shooting characteristics and the physical environment at the shooting range. This was an environmental case study of 58 male and female shooters from two indoor shooting ranges with assumed different ventilation and cleaning conditions. Information was obtained on general conditions including age, gender, tobacco and alcohol use, and shooting conditions: weapon type, number of shots fired, frequency of stays at the shooting range and hygiene habits. A venous blood sample was drawn to determine blood lead concentrations; 14 non-shooters were included as controls. Almost 60% of the shooters, hereof five out of 14 women, had a blood lead concentration above 0.48 micromol/l, a level causing long-term health concern. All controls had blood lead values below 0.17 micromol/l. Independent significant associations with blood lead concentrations above 0.48 micromol/l were found for shooting at a poorly ventilated range, use of heavy calibre weapons, number of shots and frequency of stays at the shooting range. A large proportion of Danish recreational indoor shooters had potentially harmful blood lead concentrations. Ventilation, amounts of shooting, use of heavy calibre weapons and stays at the shooting ranges were independently associated with increased blood lead. The technical check at the two ranges was performed by the Danish Technological Institute and costs were defrayed by the Danish Rifle Association. To pay for the analyses of blood lead, the study was supported by the The Else & Mogens Wedell-Wedellsborg Foundation. The Danish Regional Capital Scientific Ethics Committee approved the study, protocol number H-4-2010-130.

Background Immigrant populations in western societies have grown in their size and diversity yet evidence is incomplete for their risks of suicidality and criminal violence. We examined these correlated harmful behaviours in a national cohort. Aims (i) Compare absolute risk between first and second generation immigrants, foreign-born adoptees and native Danes by plotting cumulative incidence curves to onset of early middle age; (ii) estimate sex-specific relative risks for these immigrant type subgroups vs. native Danes; (iii) examine effect modification by higher vs. lower socio-economic status. Methods In a cohort of over two million persons, attempted suicides and violent crimes were investigated using data from multiple interlinked registers. We plotted sex-specific cumulative incidence curves and estimated incidence rate ratios. Results In the whole study cohort, 1414 people died by suicide, 46,943 attempted suicide, and 51,344 were convicted of committing a violent crime. Among all immigrant subgroups combined, compared with native Danes, relative risk of attempted suicide was greater in female immigrants (incidence rate ratio, 1.59; 95% confidence interval: CI 1.54-1.64) than in male immigrants (1.26; CI 1.20-1.32), and vice versa for relative risk of violent offending in male immigrants (2.36; CI 2.31-2.42) than in female immigrants (1.74; CI 1.62-1.87). Risk for both adverse outcomes was significantly elevated in virtually every gender-specific immigrant type subgroup examined. Violent crime risk was markedly raised in first generation immigrant males and in the Danish born male children of two immigrant parents. However, male immigrants of lower social status had lower risk of attempted suicide than their native Danish peers. Conclusion Young immigrants of both first and second generation status face serious challenges and vulnerabilities that western societies need to urgently address. Relative risk patterns for these adverse outcomes vary greatly

The duration of untreated psychosis (DUP) has been shown to have an effect on outcome after first-episode psychosis. The premise of specialized early intervention (SEI) services is that intervention in the early years of illness can affect long-term outcomes. In this study, we investigate whether DUP affects treatment response after 5 years of SEI treatment compared to 2 years of SEI treatment. As part of a randomized controlled trial testing the effect of prolonged SEI treatment 400 participants diagnosed within the schizophrenia spectrum were recruited. For this specific study participants were dichotomized based on DUP, treatment delay, and time from first symptom until start of SEI treatment. The groups were analyzed with regard to treatment response on psychopathology, level of functioning, and cognitive functioning. The participants with a short DUP had a tendency to respond better to the prolonged treatment with regards to disorganized and negative dimension. For participants with short duration from first symptom until start of SEI treatment there was a significant difference on the negative dimension favoring the prolonged OPUS treatment. The finding of an effect of prolonged treatment for participants with a short total treatment delay could mean that prolonged SEI treatment is more beneficial than treatment as usual (TAU) so long as it is provided in the early years of illness and not just in the early years after diagnosis. THE EARLIER THE BETTER: The duration of untreated psychosis influences the long-term outcomes of treatment. Nikolai Albert, at the Copenhagen Mental Health Centre, and a team of Danish researchers have investigated the effects of a specialized early intervention program (OPUS) in 400 patients diagnosed with schizophrenia spectrum disorders and compared the effects of OPUS after two and five years. Their findings suggest that five years of specialized early intervention was most beneficial when the total duration from symptom start to

The identification of causal genes or genomic regions associated with fatty acids (FA) will enhance our understanding of the pathways underlying FA synthesis and provide opportunities for changing milk fat composition through a genetic approach. The linkage disequilibrium between adjacent markers is highly consistent between the Chinese and Danish Holstein populations, such that a joint genome-wide association study (GWAS) can be performed. In this study, a joint GWAS was performed for 16 milk FA traits based on data of 784 Chinese and 371 Danish Holstein cows genotyped by a high-density bovine single nucleotide polymorphism (SNP) array. A total of 486,464 SNP markers on 29 bovine autosomes were used. Bonferroni corrections were applied to adjust the significance thresholds for multiple testing at the genome- and chromosome-wide levels. According to the analysis of either the Chinese or Danish data individually, the total numbers of overlapping SNP that were significant at the chromosome level were 94 for C14:1, 208 for the C14 index, and 1 for C18:0. Joint analysis using the combined data of the 2 populations detected greater numbers of significant SNP compared with either of the individual populations alone for 7 and 10 traits at the genome- and chromosome-wide significance levels, respectively. Greater numbers of significant SNP were detected for C18:0 and the C18 index in the Chinese population compared with the joint analysis. Sixty-five significant SNP across all traits had significantly different effects in the 2 populations. Ten FA were influenced by a quantitative trait loci (QTL) region including DGAT1. Both C14:1 and the C14 index were influenced by a QTL region including SCD1 in the combined population. Other QTL regions also showed significant associations with the studied FA. A large region (14.9-24.9 Mbp) in BTA26 significantly influenced C14:1 and the C14 index in both populations, mostly likely due to the SNP in SCD1. A QTL region (69.97-73.69 Mbp

Peripheral nerve sheath tumors (PNSTs) are frequently found in Danish cattle at slaughter. Bovine PNSTs share several gross and histopathological characteristics with the PNSTs in humans with heritable neurofibromatosis syndromes. The aim of the present study was to investigate a possible hereditary disposition to PNSTs in dairy cattle by statistical analysis performed on data from 567 cattle with PNSTs. Furthermore, a preliminary genome-wide association study (GWAS) was performed on DNA isolated from 28 affected and 28 non-affected Holstein cows to identify loci in the bovine genome involved in the development of PNSTs. PNSTs were significantly more common in the Danish Holstein breed than in other breeds with 0.49% of Danish Holsteins slaughtered during an eight-year-period having PNSTs. PNSTs also occurred significantly more frequently in the offspring of some specific Holstein sires. Examination of three generation pedigrees showed that these sires were genetically related through a widely used US Holstein sire. The PNSTs included in GWAS were histologically classified as neurofibroma-schwannoma (43%), schwannoma (36%) and neurofibroma (21%) and derived from Holstein cows with multiple PNSTs. A single SNP on chromosome 27 reached genome-wide significance. Gross and histological characteristics of bovine PNSTs are comparable to PNSTs in humans (schwannomatosis). Danish Holsteins are genetically disposed to develop PNSTs but the examined materials are insufficient to allow determination of the mode of inheritance.

[The Danish Debate on Priority Setting in Medicine--An Update].

PubMed

Pornak, S C; Raspe, H

2015-09-01

In the last years, the Danish debate about priority setting in medicine has gained new strength. This paper shows the main focuses of the current discussion based on a research of Danish primary literature. For the first time since the 1990s the Danish Council of Ethics has been involved with priority setting in medicine in a project running from 2011 to 2013. The Council emphasises the importance of legitimate processes and calls for visible values and criteria. A focus of the debate is how to deal with new expensive drugs. Politicians, physicians, health economists and the Council of Ethics have called for a national institution for priority setting in medicine. They have mainly looked to the Norwegian National Council for Priority Setting in Health Care and the British National Institute for Health and Care Excellence for inspiration. The Danish Government considered establishing a national institute for priority setting, but the plans were not put into practice. In the year 2012 a new national project was launched to create clinical guidelines. Danish doctors welcome the guidelines as a good basis for priority setting. Just like in earlier Danish priority setting debates, a coordinating institution is lacking to bundle the discussion and keep it going. The debate seems to have come to an end once again. The fact that it was seriously considered to establish an institute for priority setting is a new development. It can be expected that the discussion will be resumed in the near future, possibly the idea of an institute for priority setting will be readopted. The general conditions for priority setting in health care have improved. © Georg Thieme Verlag KG Stuttgart · New York.

The VISA-A questionnaire has proven to be a valid and reliable tool for assessing severity of Achilles tendinopathy (AT). The aim was to translate and cross-culturally adapt the VISA-A questionnaire for a Danish-speaking AT population, and subsequently perform validity and reliability tests. Translation and following cross-cultural adaptation was performed as translation, synthesis, reverse translation, expert review, and pretesting. The final Danish version (VISA-A-DK) was tested for reliability on healthy controls (n = 75) and patients (n = 36). Tests for internal consistency, validity, and structure were performed on 71 patients. VISA-A-DK showed good reliability for patients (r = 0.80 ICC = 0.79) and healthy individuals (r = 0.98 ICC = 0.97). Internal consistency was 0.73 (Cronbach's alpha). The mean VISA-A-DK score in AT patients was 51 [47-55]. This was significantly lower than healthy controls with a score of 93 (90-95). Criterion validity was considered good when comparing the scores of the Danish version with the original version in both healthy individuals and patients. VISA-A-DK is a valid and reliable instrument and has shown compatible to the original version in assessment of AT patients. VISA-A-DK is a useful tool in the assessment of AT, both in research and in a clinical setting. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To assess the availability and applicability of clinical indications from electronic prescriptions on antibiotic use in Danish general practice. Retrospective cohort register-based study including the Danish National Prescription Register. Population-based study of routine electronic antibiotic prescriptions from Danish general practice. All 975,626 patients who redeemed an antibiotic prescription at outpatient pharmacies during the 1-year study period (July 2012 to June 2013). Number of prescriptions per clinical indication. Number of antibiotic prescriptions per 1000 inhabitants by age and gender. Logistic regression analysis estimated the association between patient and provider factors and missing clinical indications on antibiotic prescriptions. A total of 2.381.083 systemic antibiotic prescriptions were issued by Danish general practitioners in the study period. We identified three main clinical entities: urinary tract infections (n = 506.634), respiratory tract infections (n = 456.354) and unspecified infections (n = 416.354). Women were more exposed to antibiotics than men. Antibiotic use was high in children under 5 years and even higher in elderly people. In 32% of the issued prescriptions, the clinical indication was missing. This was mainly associated with antibiotic types. We found that a prescription for a urinary tract agent without a specific clinical indication was uncommon. Clinical indications from electronic prescriptions are accessible and available to provide an overview of drug use, in casu antibiotic prescriptions, in Danish general practice. These clinical indications may be further explored in detail to assess rational drug use and congruence with guidelines, but validation and optimisation of the system is preferable.

Increased AβPP processing in familial Danish dementia patients.

An autosomal dominant mutation in the BRI2/ITM2B gene causes Familial Danish Dementia (FDD). We have generated a mouse model of FDD, called FDDKI, genetically congruous to the human disease. These mice carry one mutant and one wild type Bri2/Itm2b allele, like FDD patients. Analysis of FDDKI mice and samples from human patients has shown that the Danish mutation causes loss of Bri2 protein. FDDKI mice show synaptic plasticity and memory impairments. BRI2 is a physiological interactor of amyloid-β protein precursor (AβPP), a gene associated with Alzheimer's disease, which inhibits processing of AβPP. AβPP/Bri2 complexes are reduced in synaptic membranes of FDDKI mice. Consequently, AβPP metabolites derived from processing of AβPP by β-, α-, and γ-secretases are increased in Danish dementia mice. AβPP haplodeficiency prevents memory and synaptic dysfunctions, consistent with a role for AβPP-metabolites in the pathogenesis of memory and synaptic deficits. This genetic suppression provides compelling evidence that AβPP and BRI2 functionally interact. Here, we have investigated whether AβPP processing is altered in FDD patients' brain samples. We find that the levels of several AβPP metabolites, including Aβ, are significantly increased in the brain sample derived from an FDD patient. Our data are consistent with the findings in FDDKI mice, and support the hypothesis that the neurological effects of the Danish form of BRI2 are caused by toxic AβPP metabolites, suggesting that Familial Danish and Alzheimer's dementias share common pathogenic mechanisms.

Objective Exposure to electric shock has been associated with an increased risk of developing delayed cardiac arrhythmias and cardiac diseases. We examined whether electric shock patients have an increased risk of developing cardiac disease, cardiac arrhythmias or death compared with the general Danish population. Design Matched cohort study. Setting A nationwide study in Denmark from 1994 to 2011. Participants We identified 11 462 Danish patients who visited an emergency ward or were admitted to a hospital due to electric shock from 1994 to 2011. Each patient was matched for age and sex with five random controls from the Danish population. Main outcome measures Mortality, cardiac procedures and cardiac diseases following electric shock. Results A total of 7390 electric shock patients were seen at an emergency ward and 4072 electric shock patients were admitted to a hospital. The median patient age was 28.6 years (Q1–Q3, 21.3–37.7) for the emergency ward patients and 26.4 years (Q1–Q3, 18.3–37.4) for admitted patients. In both groups, most patients were male (74.0% and 76.8%). Few of the electric shock patients had a record of cardiovascular disease at baseline (364/11 462, 3.2%). The 5-year cumulative incidence of death was 0.47% (95% CI 0.29% to 0.65%) for emergency ward patients and 1.04% (95% CI 0.71% to 1.37%) for admitted patients. No difference in 5-year survival was observed compared with matched controls (emergency ward, p=0.10; admitted patients, p=0.80). Fewer than four patients received a pacemaker within 30 days. Conclusions This nationwide study did not demonstrate an increase in mortality among patients seen at hospitals after accidental electric shock compared with a background population. Cardiac procedures and diseases following electric shock were very rare. We suggest that nearly all patients can be discharged safely from the emergency room after electric shock without further observation. PMID:28851780

The aim of this study was to investigate the prevalence of xenobiotic substances, such as caffeine, nicotine and illicit drugs (eg, cannabis and cocaine), in blood samples from first-trimester Danish pregnant women unaware of the screening. A cross - sectional study examined 436 anonymised residual blood samples obtained during 2014 as part of the nationwide prenatal first-trimester screening programme. The samples were analysed by ultra performance liquid chromatography with high-resolution time-of-flight mass spectrometry. An antenatal clinic in a Danish city with 62 000 inhabitants, where >95% of pregnant women joined the screening programme. The prevalence and patterns of caffeine, nicotine, medication and illicit drug intake during the first trimester of pregnancy. The prevalence of prescription and over-the-counter drug detection was 17.9%, including acetaminophen (8.9%) and antidepressants (3.0%), of which citalopram (0.9%) was the most frequent. The prevalence of illegal drugs, indicators of smoking (nicotine/cotinine) and caffeine was 0.9%, 9.9%, and 76.4%, respectively. Only 17.4% of women had no substance identified in their sample. This study emphasises the need for further translational studies investigating lifestyle habits during pregnancy, as well as the underlying molecular mechanisms through which xenobiotic substances may affect placental function and fetal development. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

In the Copenhagen mammography screening program from 1991 to 2001, mammographic density was classified either as fatty or mixed/dense. This dichotomous mammographic density classification system is unique internationally, and has not been validated before. To compare the Danish dichotomous mammographic density classification system from 1991 to 2001 with the density BI-RADS classifications, in an attempt to validate the Danish classification system. The study sample consisted of 120 mammograms taken in Copenhagen in 1991-2001, which tested false positive, and which were in 2012 re-assessed and classified according to the BI-RADS classification system. We calculated inter-rater agreement between the Danish dichotomous mammographic classification as fatty or mixed/dense and the four-level BI-RADS classification by the linear weighted Kappa statistic. Of the 120 women, 32 (26.7%) were classified as having fatty and 88 (73.3%) as mixed/dense mammographic density, according to Danish dichotomous classification. According to BI-RADS density classification, 12 (10.0%) women were classified as having predominantly fatty (BI-RADS code 1), 46 (38.3%) as having scattered fibroglandular (BI-RADS code 2), 57 (47.5%) as having heterogeneously dense (BI-RADS 3), and five (4.2%) as having extremely dense (BI-RADS code 4) mammographic density. The inter-rater variability assessed by weighted kappa statistic showed a substantial agreement (0.75). The dichotomous mammographic density classification system utilized in early years of Copenhagen's mammographic screening program (1991-2001) agreed well with the BI-RADS density classification system.

An Early Danish Computer Game

NASA Astrophysics Data System (ADS)

Jørgensen, Anker Helms

This paper reports on the development of Nimbi, which is an early computer game implemented at the Danish Computer Company Regnecentralen in 1962-63. Nimbi is a variant of the ancient game Nim. The paper traces the primary origins of the development of Nimbi. These include a mathematical analysis from 1901 of Nim that “killed the game” as the outcome could be predicted quite easily; the desire of the Danish inventor Piet Hein to make a game that eluded such analyses; and the desire of Piet Hein to have computers play games against humans. The development of Nimbi was successful in spite of considerable technical obstacles. However, it seems that the game was not used for publicizing the capabilities of computers - at least not widely - as was the case with earlier Nim implementations, such as the British Nim-playing computer Nimrod in 1951.

The possible association between employment in horticulture with potential exposure to pesticides and female infertility was examined by identification of women with hospital contact due to infertility and working in horticulture through the Danish Occupational Hospitalization Register. This follow-up study gave a standardized incidence ratio of 1.06 (95% confidence interval: 0.84-1.32) for treatment of infertility in women working in horticulture compared with the standard population and did not confirm that women working in the horticultural industry are at increased risk for infertility.

The aim of the study was to examine occupational accidents reported from non-passenger merchant ships registered in the Danish International Ship Register in 2010-2012, with a focus on analysing nationality differences in the risk of getting injured in an accident. Data about notified occupational accidents were collected from notifications sent to the Danish Maritime Authority and from records of contact with Danish Radio Medical. Events were matched by personal identification and accident data to create a unified database. Stratified cumulative time spent on board by seafarers was used to calculate accident rates. Incidence rates of different nationalities were compared by Poisson regression. Western European seafarers had an overall accident rate of 17.5 per 100000 person-days, which proved to be significantly higher than that of Eastern European, South East Asian and Indian seaman (adjusted incidence rate ratio 0.53, 0.51 and 0.74, respectively), although differences decreased over the investigated period. Smaller but in most cases still significant discrepancies were observed for serious injuries. The back injury rate of Western European employees was found especially high, while eye injuries seem to be more frequent among South East Asian workers. The study identified substantial differences between nationalities in the rate of various accidents reported from merchant ships sailing under the Danish flag. The differences may be attributed to various factors such as safety behaviour. Investigation of special injury types and characterisation of effective elements of safety culture can contribute to the improvement of workplace safety in the maritime sector.

 Optoacoustic imaging with ultrasound (OPUS) can assess in-vivo perfusion/oxygenation through surrogate measures of oxy, deoxy and total hemoglobin content in tissues. The primary aim of our study was to evaluate the ability of OPUS to detect physiological changes in the breast during the menstrual cycle and to determine qualitative/quantitative metrics of normal parenchymal tissue in pre-/post-menopausal women. The secondary aim was to assess the technique's repeatability.  We performed a prospective ethically approved study in volunteers using OPUS (700, 800 and 850 nm wavelengths) in the proliferative/follicular and secretory phase of the menstrual cycle. Regions of interest (ROIs) were drawn on the most superficial region of fibroglandular tissue and same-day intra-observer repeatability was assessed. We used t-tests to interrogate differences in the OPUS measurements due to hormonal changes and interclass correlation coefficients/Bland-Altman plots to evaluate the repeatability of mean ROI signal intensities.  22 pre-menopausal and 8 post-menopausal volunteers were recruited. 21 participants underwent repeatability examinations. OPUS intensity values were significantly higher (p < 0.0001) at all excitation wavelengths in the secretory compared to the proliferative/follicular phase. Post-menopausal volunteers showed similar optoacoustic values to the proliferative/follicular phase of pre-menopausal volunteers. The repeatability of the technique was comparable to other handheld ultrasound modalities.  OPUS detects changes in perfusion/vascularity related to the menstrual cycle and menopausal status of breast parenchyma. © Georg Thieme Verlag KG Stuttgart · New York.

The perceived usefulness of incident reporting systems is an important motivational factor for reporting. The usefulness may be facilitated by well-established feedback mechanisms and by learning processes. The aim of this study was to investigate how feedback mechanisms and learning processes were implemented at four Danish hospital units all located in one of the five Danish regions. Based on the concepts of feedback and learning from incident processes, a questionnaire was developed and distributed to 335 patient safety representatives from 200 departments at four Danish hospital units in one of the five Danish regions. The study showed that external reporters were rarely contacted for dialogue, grouped front-line staff were sparsely involved in the learning process, few evaluated the effectiveness of implemented interventions and personal factors were frequently perceived as a primary contributory factor to these incidents. In contrast, the patient safety representatives perceived their competencies as sufficient for the job, internal reporters were often contacted for dialogue, evaluation was widely used and management supported the work with incident reports. The results of the study identified several shortcomings in the implementation of learning processes and feedback mechanisms. The apparent existence of a person-focused approach stands out as an element of notice. The insufficient implementation we observed indicates that there is room for improvement in the efforts made to maximise learning from incidents in the investigated population. not relevant. not relevant.

Studies have shown that children later diagnosed with autism spectrum disorders (ASD) in their first years of life might show symptoms in main developmental areas and that these signs might be sensed by the parents. The present study investigated in a large birth cohort if children later diagnosed with ASD had deviations at 6 and 18 months in areas such as the ability to self-regulate emotions, feeding, and sleeping. The study was based on prospective information collected from 76,322 mothers who participated in the Danish National Birth Cohort. When the children reached an average age of 11 years, 973 children with ASD and a control group of 300 children with intellectual disability (IDnoASD) were identified via Danish health registries. Associations were found between short periods of breast-feeding and the children later diagnosed with ASD and IDnoASD as well as associations at 18 months to deviations in regulation of emotions and activity. The similarities in these associations emphasize how difficult it is to distinguish between diagnoses early in life. © 2018 Michigan Association for Infant Mental Health.

The article series provides a written and pictorial account of the Danish pharmaceutical industry's products from their introduction until about 1950. Part 6 deals with products from A/S Pharmacia. A/S Pharmacia was established in Copenhagen in 1922 as a Danish limited company by the enterprising pharmacist Edward Jacobsen. Pharmacia was not Jacobsen's first pharmaceutical company as previously he had established a pharmaceutical agency already in 1913 which in 1919 was reorganized to a limited company by the name of A/S Edward Jacobsen. This agency was later extended to include a production of generics. Jacobsen remained the co-owner and manager of Pharmacia until 1934 where he resigned and established another company, A/S Ejco, for the manufacture of generics. It is worth mentioning that already in 1911 a Swedish pharmaceutical company was established named AB Pharmacia. Today we do not know whether Edward Jacobsen knew about this Swedish company. Later on in 1936 AB Pharmacia and A/S Pharmacia made a contract concerning mutual market sharing, and a research cooperation was brought about between the two companies which resulted in an increase of turnover for A/S Pharmacia. In 1955 the cooperation between the two companies was increased as the Swedish company joined as principal shareholder with the purpose of continuing and developing the Danish company as an independent pharmaceutical company with its own research and development as well as manufacture, control and marketing. Therefore Pharmacia in Denmark was able to establish a synthesis factory in Koge and move the domicile to new premises in Hillered. In 1993 Pharmacia was presented in a printed matter as "The largest Nordic pharmaceutical company" as a result of the merger between the Swedish Kabi Pharmacia, formerly established by a merger between Kabi Vitrum and AB Pharmacia, and the Italian Farmitalia Carlo Erba. Only two years later in 1995 Pharmacia merged with the American pharmaceutical company The

The paper analyses the development of the total number of journal articles indexed in the Medline database published by authors affiliated to Denmark 1989-1998 in medicine compared to the development in the European Union during the same period. The publication analysis is then compared to the citation impact of articles published in the central journals indexed in Science Citation Index (ISI) 1987-1996 through use of the National Science Indicators (NIS, ISI) database. The total number of Danish journal articles has remained relatively constant compared to a 50% increase in the EU as a whole. The number of Danish articles published in central journals, however, has increased by 20% (compared to 27% for the EU) and the number of citations obtained by these articles by 58% (compared to 66% for the EU) in the 1987-1996 period. By population, Denmark ranked third in total number of articles in 1998. In conclusion, Denmark is very active in medical research but neither the quantity nor the quality of Danish medical research has increased at the same rate as the EU average.

To investigate the risk of tumours in the central nervous system among Danish mobile phone subscribers. Nationwide cohort study. Denmark. All Danes aged ≥ 30 and born in Denmark after 1925, subdivided into subscribers and non-subscribers of mobile phones before 1995. Risk of tumours of the central nervous system, identified from the complete Danish Cancer Register. Sex specific incidence rate ratios estimated with log linear Poisson regression models adjusted for age, calendar period, education, and disposable income. 358,403 subscription holders accrued 3.8 million person years. In the follow-up period 1990-2007, there were 10,729 cases of tumours of the central nervous system. The risk of such tumours was close to unity for both men and women. When restricted to individuals with the longest mobile phone use--that is, ≥ 13 years of subscription--the incidence rate ratio was 1.03 (95% confidence interval 0.83 to 1.27) in men and 0.91 (0.41 to 2.04) in women. Among those with subscriptions of ≥ 10 years, ratios were 1.04 (0.85 to 1.26) in men and 1.04 (0.56 to 1.95) in women for glioma and 0.90 (0.57 to 1.42) in men and 0.93 (0.46 to 1.87) in women for meningioma. There was no indication of dose-response relation either by years since first subscription for a mobile phone or by anatomical location of the tumour--that is, in regions of the brain closest to where the handset is usually held to the head. In this update of a large nationwide cohort study of mobile phone use, there were no increased risks of tumours of the central nervous system, providing little evidence for a causal association.

Objective To investigate the risk of tumours in the central nervous system among Danish mobile phone subscribers. Design Nationwide cohort study. Setting Denmark. Participants All Danes aged ≥30 and born in Denmark after 1925, subdivided into subscribers and non-subscribers of mobile phones before 1995. Main outcome measures Risk of tumours of the central nervous system, identified from the complete Danish Cancer Register. Sex specific incidence rate ratios estimated with log linear Poisson regression models adjusted for age, calendar period, education, and disposable income. Results 358 403 subscription holders accrued 3.8 million person years. In the follow-up period 1990-2007, there were 10 729 cases of tumours of the central nervous system. The risk of such tumours was close to unity for both men and women. When restricted to individuals with the longest mobile phone use—that is, ≥13 years of subscription—the incidence rate ratio was 1.03 (95% confidence interval 0.83 to 1.27) in men and 0.91 (0.41 to 2.04) in women. Among those with subscriptions of ≥10 years, ratios were 1.04 (0.85 to 1.26) in men and 1.04 (0.56 to 1.95) in women for glioma and 0.90 (0.57 to 1.42) in men and 0.93 (0.46 to 1.87) in women for meningioma. There was no indication of dose-response relation either by years since first subscription for a mobile phone or by anatomical location of the tumour—that is, in regions of the brain closest to where the handset is usually held to the head.

Vaccines may have non-specific effects as suggested mainly in mortality studies from low-income countries. The objective was to examine the effects of BCG and smallpox vaccinations on subsequent risk of lymphoma and leukaemia in a Danish population experiencing rapid out-phasing of these vaccines. In a background cohort (N=47,622) from the Copenhagen School Health Records Register, cases of leukaemia (N=20) and lymphoma (N=51) were identified through the Danish Cancer Registry. The vaccination status of the cases was compared with the vaccination status of a 5% random sample (N=2073) of the background cohort and analysed in a case-cohort design. BCG vaccination reduced the risk of lymphomas (HR=0.49 (95% CI: 0.26-0.93)), whereas smallpox vaccination did not (HR=1.32 (0.56-3.08)). With the small number of leukaemia cases, the analysis of leukaemia had limited power (BCG vaccination HR=0.81 (0.31-2.16); smallpox vaccination HR=1.32 (0.49-3.53)). The present study with very reliable vaccine history information indicates a beneficial effect of BCG vaccination on the risk of lymphomas.

Firefighters are exposed to multiple cardiovascular hazards, but few epidemiological studies have addressed their cardiovascular morbidity. The objective of this study was therefore to examine the incidence of cardiovascular diseases (CVD) in Danish firefighters. We used individual historical employment records on 11.691 male Danish firefighters supplied by trade unions and fire agencies. The Supplementary Pension Fund Register was used to establish two occupational reference groups (a random sample from the male employed population and military employees). Information on CVD incidence was retrieved from the nationwide Danish National Patient Registry. SIRs and Poisson regression analyses (incidence rate ratio) were used for estimation of risks, including 95% CIs. In comparison with the population sample, the age-adjusted and calendar time-adjusted SIR for all CVDs combined was increased in firefighters (SIR=1.10, 95% CI 1.05 to 1.15). The risk was also elevated for the most frequent outcomes, including angina pectoris (SIR=1.16, 95% CI 1.08 to 1.24), acute myocardial infarction (SIR=1.16, 95% CI 1.06 to 1.26), chronic ischaemic heart disease (SIR=1.15, 95% CI 1.06 to 1.24) and atrial fibrillation/flutter (SIR=1.25, 95% CI 1.14 to 1.36). This analysis showed the most elevated SIRs for CVD in full-time firefighters compared with part-time/volunteer firefighters. Both types of firefighters employed <15 years had an increased risk of CVD. Similar risk patterns appeared in comparisons with the military. Internal analysis supported external findings. The risk of overall CVD, including the most frequent subtypes was modestly increased in Danish firefighters and was most elevated in full-time firefighters compared with other male employees. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The medical profession and hospital practice have changed over the last decades without a concomitant change in Danish clerkships. Therefore, the aim of this study was to analyze learning and supervision in clerkships and to discuss how traditional clerkship learning matches a modern effective hospital environment. A qualitative field study based on 38 days of observations ( asymptotically equal to 135 hours) with 6 students in 8th Semester in 2 internal medical and 3 surgical wards at 2 teaching hospitals in Aarhus County during 2003. The 6 students were interviewed prior to and following clerkship. Data were coded using Ethnograph and analyzed qualitatively. The students typically participated in 6 learning activities: morning reports, ward rounds, out-patient clinics, on call, clerking, and operating theatres. A common feature for the first 3 activities was the students' observational role in contrast to their more active role in the latter 3 activities. Supervision was primarily indirect as the doctors worked and thereby served as tacit role models. When direct, the supervision was didactic and characterized by information transfer. A clerkship offers important learning opportunities for students. They are exposed to many patients and faced with various clinical problems. However, the benefit of students learning in authentic environments is not fully utilized, and the didactic supervision used by doctors hardly matches the learning conditions in a busy hospital. Consequently, we need to reassess the students' roles and doctors' supervisory methods.

Diet has a significant impact on health, and ensuring that the population eats a healthy diet remains a public health challenge. Research is needed in order to improve the palatability of a healthy diet and make it attractive to the consumer. It has also been suggested that dietary recommendations should be tailored to regional conditions. The OPUS (Optimal well-being, development and health for Danish children through a healthy New Nordic Diet) project investigates whether it is possible to develop a healthy New Nordic Diet (NND) that is palatable, environmentally friendly and based on foods originating from the Nordic region. The present paper describes the overall guidelines for the NND, developed and investigated in the multidisciplinary, 5-year OPUS research project. All guidelines are described in relation to the key principles: health, gastronomic potential and Nordic identity, and sustainability. The NND is described by the overall guidelines: (i) more calories from plant foods and fewer from meat; (ii) more foods from the sea and lakes; and (iii) more foods from the wild countryside. These overall guidelines result in a set of proposed dietary components which will be presented in a subsequent paper. Both the guidelines and the diet are composed taking the potential health-promoting properties and Nordic identity of the NND into account, as well as concern for environmental issues and gastronomic potential.

[Medicine, music, friendship and prejudices: Billroth I and Billroth II, the string quartets Opus 51, N° 1 and N° 2 by Johannes Brahms].

The great German surgeon Theodor Billroth and the imaginative and creative composer Johannes Brahms had a very close friendship centered on musical activities, that lasted for more than thirty years while they lived and worked in Zurich and Vienna, during the second half of the Nineteenth Century. Billroth, besides his all-consuming medical activities, had time to be a musical enthusiast who directed orchestras, played the violin in chamber music groups, and wrote musical criticism for newspapers. The common affection between these two creative giants is documented by their abundant and effusive correspondence, by the constant requests by Brahms of Billroth's opinions regarding his compositions, and by the positive and stimulating answers that Billroth gave to these requests. Billroth opened his house for musical evenings to play Brahms chamber compositions for the first time, and Brahms dedicated his two Opus 51 string quartets Nos. 1 and 2, known in the musical milieu as Billroth I and II, to his physician friend. Unfortunately, the close bonds between these two geniuses weakened towards the end of their lives as a result of Billroth's becoming intolerant to the lack of social refinements and gruff behavior of the composer. This baffling intolerance of Billroth to his friend Brahms can be better understood after reading Billroth's writings in his book The Medical Sciences in the German Universities. A Study in the History of Civilization. There Billroth expresses strong prejudices against potential medical students of humble social origins, such as those of Brahms, coupled to a primitive anti-Semitism.

Otitis media is one of the most common diseases in small children. This underlines the importance of optimizing diagnostics and treatment of the condition. Recent literature points toward a stricter approach to diagnosing acute otitis media (AOM). Moreover, ventilating tube treatment for recurrent AOM (RAOM) and chronic otitis media with effusion (COME) has become the most frequently performed surgical procedure in pre-school children. Therefore, the Danish Health and Medicines Authority and the Danish Society of Otorhinolaryngology, Head and Neck Surgery deemed it necessary to update the Danish guidelines regarding the diagnostic criteria for acute otitis media and surgical treatment of RAOM and COME. The GRADE system (The Grading of Recommendations Assessment, Development and Evaluation) was used in order to comply with current standards of evidence assessment in formulation of recommendations. An extensive literature search was conducted between July and December 2014. The quality of the existing literature was assessed using AGREE II (Appraisal of Guidelines for Research & Evaluation), AMSTAR (assessing the Methodological Quality of Systematic Reviews), QUADAS-2 (Quality of Diagnostic Accuracy Studies), Cochrane Risk of Bias Tool for randomized trials and ACROBAT-NRSI (A Cochrane Risk of Bias Assessment Tool for Non-Randomized Studies). The working group consisted of otolaryngologists, general practitioners, pediatricians, microbiologists and epidemiologists. Recommendations for AOM diagnosis, surgical management for RAOM and COME, including the role of adenoidectomy and treatment of ventilating tube otorrhea, are proposed in the guideline.

Immigrants, refugees, and their descendants comprise 12% of Denmark's population. Some of these people do not speak or understand Danish well enough to communicate with the staff in a healthcare setting and therefore need interpreter services. Interpretation through video conferencing equipment (video interpretation) is frequently used and creates a forum where the interpreter is not physically present in the medical consultation. The aim of this study was to investigate the attitudes to and experiences with video interpretation among charge nurses in a Danish university hospital. An electronic questionnaire was sent to 99 charge nurses. The questionnaire comprised both closed and open-ended questions. The answers were analysed using descriptive statistics and thematic text condensation. Of the 99 charge nurses, 78 (79%) completed the questionnaire. Most charge nurses, 21 (91%) of the daily/monthly users, and 21 (72%) of the monthly/yearly users, said that video interpretation increased the quality of their conversations with patients. A total of 19 (24%) departments had not used video interpretation within the last 12 months. The more the charge nurses used video interpretation, the more satisfied they were. Most of the charge nurses using video interpretation expressed satisfaction with the technology and found it easy to use. Some charge nurses are still content to allow family or friends to interpret. To reach its full potential, video interpretation technology has to be reliable and easily accessible for any consultation, including at the bedside.

To determine the positive predictive values for stroke discharge diagnoses, including subarachnoidal haemorrhage, intracerebral haemorrhage and cerebral infarction in the Danish National Patient Register. Participants in the Danish cohort study Diet, Cancer and Health with a stroke discharge diagnosis in the National Patient Register between 1993 and 2009 were identified and their medical records were retrieved for validation of the diagnoses. A total of 3326 records of possible cases of stroke were reviewed. The overall positive predictive value for stroke was 69.3% (95% confidence interval (CI) 67.8-70.9%). The predictive values differed according to hospital characteristics, with the highest predictive value of 87.8% (95% CI 85.5-90.1%) found in departments of neurology and the lowest predictive value of 43.0% (95% CI 37.6-48.5%) found in outpatient clinics. The overall stroke diagnosis in the Danish National Patient Register had a limited predictive value. We therefore recommend the critical use of non-validated register data for research on stroke. The possibility of optimising the predictive values based on more advanced algorithms should be considered.

Caregiving and early infant crying in a danish community.

PubMed

Alvarez, Marissa

2004-04-01

Maternal caregiving and fussing/crying in Danish infants at 3, 6, and 12 weeks were examined using self-report scales and 24-hour behavior diaries. Mothers reported practices commonly associated with responsive caregiving: frequent feeding, prompt response to infant cries, and considerable time holding the infant. Fuss/cry durations peaked in the first 2 months, were highest in evenings, and decreased approximately 50% by 12 weeks. Fussing was the majority behavior, and 9.2% of the infants fussed and cried more than 3 hours per day. In contrast with other Western studies, 24-hour fuss/cry durations were lower, and fussing accounted for up to 80% of total distress. Danish caregiving practices may partially explain the lower durations of infant distress and the lower ratio of cry to fuss. However, some infants fuss/cry a great deal despite sensitive care, which may reflect individual differences in infant maturation of behavior regulation.

In light of the excess early mortality in schizophrenia, mainly due to physical illnesses, we investigated medical comorbidity, use of medication, and healthcare utilization among individuals with schizophrenia who survived into older ages to uncover potential factors contributing to their longevity. A nationwide register-based case-control study comparing 70-year-olds with and without schizophrenia. Cases were drawn from the Danish Psychiatric Central Register. Age- and sex-matched controls were drawn from the general population via the Civil Registration System. All Danish inhabitants who were diagnosed and registered with early onset schizophrenia in 1970-1979 and still alive at age 70 years. Controls alive at age 70 years. Chronic medical comorbidity, medications, and inpatient and outpatient healthcare utilization extracted from Danish healthcare registers. Older adults with schizophrenia did not differ from controls with regard to registered chronic medical illnesses, but were significantly less likely to receive medication for cardiovascular diseases (OR: 0.65; 99.29% CI: 0.50, 0.83) and more likely to be treated with analgesics (OR: 1.46; 99.29% CI: 1.04, 2.05). Overall, hospital admissions and number of days hospitalized were equal to controls, but with significantly fewer general medical outpatient contacts (RR: 0.37; 98.75% CI: 0.24, 0.55). Because the literature suggests that excess mortality continues into old age, it is possible that medical diseases were under-registered and/or under-treated. Focus on adequate medical treatment, in particular for cardiovascular disease, is needed. Future integration of psychiatric and general medical healthcare, especially outpatient care, might further optimize health outcomes for older adults with schizophrenia.

Exercise during pregnancy is associated with health benefits for both the mother and the fetus, and is therefore recommended in several national guidelines. Only few studies investigate whether these guideline recommendations are met. The aims of this study were 1. To assess the prevalence of pregnant women meeting the Danish recommendations for exercise during early pregnancy, 2. To identify pre-pregnancy factors associated with a lower probability for meeting the recommendations, and 3. To describe which types of exercise pregnant women prefer before and during pregnancy. We conducted a cross-sectional study based on a questionnaire during the first trimester among 7,915 women participating in the prospective Copenhagen Pregnancy Cohort. Associations were estimated by multivariate regression analyses. In early pregnancy, 38 % of the study population met the recommendation for exercise from the Danish Health and Medicines Authority (≥3.5 hours a week). Multiparity, previous miscarriage use of assisted reproductive technology, no engagement in exercise before pregnancy, smoking, pregnancy following assisted reproductive technology, overweight, not understanding Danish language and a low educational level were all factors associated a lower probability for meeting the recommendations. The preferred types of exercise before and during pregnancy were bicycling, brisk walking, running and strength training. The proportion of women engaged in any type of exercise decreased in early pregnancy with the exception of swimming and aquatic exercise. In this cohort, more than one-third met the Danish recommendation for exercise during early pregnancy. Exercise in pregnancy is still an issue to address because the most vulnerable groups of pregnant women do not exercise. This is a cause of concern because it may reflect social inequalities in health and highlights the need for a structural and systematic approach to preconception care and early antenatal counselling.

External compression headache is defined as a headache caused by an external physical compression applied on the head. It affects about 4% of the general population; however, certain populations (e.g. construction workers and military personnel) with particular needs of headwear or helmet are at higher risk of developing this type of headache. External compression headache is poorly studied in relation to specific populations. This study aimed to investigate the prevalence and pattern of helmet-induced external compression headache among Danish military personnel of the Northern Jutland region in Denmark. Data acquisition was based on a custom-made questionnaire delivered to volunteers who used helmets in the Danish military service and who agreed to participate in this study. The military of the Northern Jutland region of Denmark facilitated recruitment of the participants. The questionnaires were delivered on paper and the collected (anonymous) answers (total 279) were used for further analysis. About 30% of the study participants reported headache in relation to wearing a military helmet. Headache was defined as a pressing pain predominantly in the front of the head with an average intensity of 4 on a visual analogue scale of 0 (no pain) to 10 (worst pain imaginable). It was also found that helmets with different designs influenced both the occurrence of headache and its characteristics. This study is the first to demonstrate the prevalence and pattern of compression headache among military personnel in North Jutland, Denmark. The findings of this study call for further attention to helmet-induced external compression headache and strategies to minimize the burden.

Exposure to electric shock has been associated with an increased risk of developing delayed cardiac arrhythmias and cardiac diseases. We examined whether electric shock patients have an increased risk of developing cardiac disease, cardiac arrhythmias or death compared with the general Danish population. Matched cohort study. A nationwide study in Denmark from 1994 to 2011. We identified 11 462 Danish patients who visited an emergency ward or were admitted to a hospital due to electric shock from 1994 to 2011. Each patient was matched for age and sex with five random controls from the Danish population. Mortality, cardiac procedures and cardiac diseases following electric shock. A total of 7390 electric shock patients were seen at an emergency ward and 4072 electric shock patients were admitted to a hospital. The median patient age was 28.6 years (Q1-Q3, 21.3-37.7) for the emergency ward patients and 26.4 years (Q1-Q3, 18.3-37.4) for admitted patients. In both groups, most patients were male (74.0% and 76.8%). Few of the electric shock patients had a record of cardiovascular disease at baseline (364/11 462, 3.2%). The 5-year cumulative incidence of death was 0.47% (95% CI 0.29% to 0.65%) for emergency ward patients and 1.04% (95% CI 0.71% to 1.37%) for admitted patients. No difference in 5-year survival was observed compared with matched controls (emergency ward, p=0.10; admitted patients, p=0.80). Fewer than four patients received a pacemaker within 30 days. This nationwide study did not demonstrate an increase in mortality among patients seen at hospitals after accidental electric shock compared with a background population. Cardiac procedures and diseases following electric shock were very rare. We suggest that nearly all patients can be discharged safely from the emergency room after electric shock without further observation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The pathogenesis of rosacea is unclear, but increased matrix metalloproteinase target tissue activity appears to play an important role. Parkinson disease and other neurodegenerative disorders also display increased matrix metalloproteinase activity that contribute to neuronal loss. To investigate the risk of incident (new-onset) Parkinson disease in patients with rosacea. A nationwide cohort study of the Danish population was conducted using individual-level linkage of administrative registers. All Danish citizens 18 years or older from January 1, 1997, to December 31, 2011 (N = 5 472 745), were included. Data analysis was conducted from June 26 to July 27, 2015. The main outcome was a diagnosis of Parkinson disease. Incidence rates (IRs) per 10 000 person-years were calculated, and incidence rate ratios (IRRs) adjusted for age, sex, socioeconomic status, smoking, alcohol abuse, medication, and comorbidity were estimated by Poisson regression models. A total of 5 404 692 individuals were included in the reference population; of these, 22 387 individuals (9812 [43.8%] women; mean [SD] age at diagnosis, 75.9 [10.2] years) received a diagnosis of Parkinson disease during the study period and 68 053 individuals (45 712 [67.2%] women; mean age, 42.2 [16.5] years) were registered as having rosacea. The IRs of Parkinson disease per 10 000 person-years were 3.54 (95% CI, 3.49-3.59) in the reference population and 7.62 (95% CI, 6.78-8.57) in patients with rosacea. The adjusted IRR of Parkinson disease was 1.71 (95%, CI 1.52-1.92) in patients with rosacea compared with the reference population. There was a 2-fold increased risk of Parkinson disease in patients classified as having ocular rosacea (adjusted IRR, 2.03 [95% CI, 1.67-2.48]), and tetracycline therapy appeared to reduce the risk of Parkinson disease (adjusted IRR, 0.98 [95% CI, 0.97-0.99]). Rosacea constitutes an independent risk factor for Parkinson disease. This association could be due to shared

Purpose Musculoskeletal disorders (MSDs), sickness absence and premature retirement are highly prevalent among eldercare workers. We conducted a prospective observational workplace study with the main purpose to investigate longitudinal associations between physical and psychosocial working conditions and occurrence of MSD and its consequences (pain-related interference with daily work activities and sickness absence) among Danish eldercare workers. Participants At 20 Danish nursing homes, a total of 941 eldercare workers employed in day and evening shifts were invited to the study. Of those, 553 participated in the baseline measurements, and 441 completed the total period of 12 months follow-up. Findings to date Data were collected from September 2013 to January 2016. Physical and psychosocial working conditions were assessed with multiple methods (observations, accelerometer measurements and work schedules), and multiple levels of information (nursing home, ward, resident and eldercare worker) were incorporated in the data collection. MSD and the consequences hereof were assessed monthly during a 1-year follow-up. Study participants and non-participants were comparable on most of the 27 sociodemographic, health and working condition characteristics at baseline. The exceptions were higher neck–shoulder pain intensity, less sickness absence, more exposure to negative behaviour from residents and a higher percentage of working day shifts and fewer evening shifts among participants compared with non-participants. Future plans The first publications will report on the associations of physical and psychosocial working conditions with occurrence of MSD and its consequences. In addition, the cohort gives the opportunity to investigate the importance of organisational, management and team factors for distribution of physical work demands and development of MSD among the workers. This will provide important knowledge for future workplace interventions to reduce MSD and

The Patient Activation Measure (PAM) is a measure that assesses patient knowledge, skill, and confidence for self-management. This study validates the Danish translation of the 13-item Patient Activation Measure (PAM13) in a Danish population with dysglycaemia. 358 people with screen-detected dysglycaemia participating in a primary care health education study responded to PAM13. The PAM13 was translated into Danish by a standardised forward-backward translation. Data quality was assessed by mean, median, item response, missing values, floor and ceiling effects, internal consistency (Cronbach's alpha and average inter-item correlation) and item-rest correlations. Scale properties were assessed by Rasch Rating Scale models. The item response was high with a small number of missing values (0.8-4.2%). Floor effect was small (range 0.6-3.6%), but the ceiling effect was above 15% for all items (range 18.6-62.7%). The alpha-coefficient was 0.89 and the average inter-item correlation 0.38. The Danish version formed a unidimensional, probabilistic Guttman-like scale explaining 43.2% of the variance. We did however, find a different item sequence compared to the original scale. A Danish version of PAM13 with acceptable validity and reliability is now available. Further development should focus on single items, response categories in relation to ceiling effects and further validation of reproducibility and responsiveness.

Objective Danish medical registries are widely used for cardiovascular research, but little is known about the data quality of cardiac interventions. We computed positive predictive values (PPVs) of codes for cardiac examinations, procedures and surgeries registered in the Danish National Patient Registry during 2010–2012. Design Population-based validation study. Setting We randomly sampled patients from 1 university hospital and 2 regional hospitals in the Central Denmark Region. Participants 1239 patients undergoing different cardiac interventions. Main outcome measure PPVs with medical record review as reference standard. Results A total of 1233 medical records (99% of the total sample) were available for review. PPVs ranged from 83% to 100%. For examinations, the PPV was overall 98%, reflecting PPVs of 97% for echocardiography, 97% for right heart catheterisation and 100% for coronary angiogram. For procedures, the PPV was 98% overall, with PPVs of 98% for thrombolysis, 92% for cardioversion, 100% for radiofrequency ablation, 98% for percutaneous coronary intervention, and 100% for both cardiac pacemakers and implantable cardiac defibrillators. For cardiac surgery, the overall PPVs was 99%, encompassing PPVs of 100% for mitral valve surgery, 99% for aortic valve surgery, 98% for coronary artery bypass graft surgery, and 100% for heart transplantation. The accuracy of coding was consistent within age, sex, and calendar year categories, and the agreement between independent reviewers was high (99%). Conclusions Cardiac examinations, procedures and surgeries have high PPVs in the Danish National Patient Registry. PMID:27940630

We aimed to assess psychometric properties, including internal consistency, reliability, and clinical validity of the Danish version of the Voice Handicap Index (VHI). A cross-sectional survey study was carried out. For validation, the existing nonvalidated Danish version of the VHI was used. Data from 208 patients with voice disorders of different etiology (neurogenic, functional, and structural) and a control group of 85 vocally healthy individuals were included. A test-retest reliability analysis of 42 patients and 45 control persons was performed. The internal consistency, test-retest reliability, and clinical validity of the questionnaire were assessed. Internal consistency was high with a Cronbach α >0.90 for both the patient and control group. Test-retest reliability measured as intraclass correlation coefficient was good with 0.93 (95% confidence interval [95% confidence interval]: 0.87-0.96) for patients and 0.78 (95% confidence interval: 0.63-0.87) for the control group which indicates sufficient reliability of the questionnaire. The Danish VHI has good clinical validity as it has a strong correlation between patient's perception of the severity of their voice disorder and the VHI score from the Spearman correlation of 0.69. The existing Danish version of the VHI has been thoroughly validated and found to be in line with the original VHI from Jacobsen et al. It showed good internal consistency, test-retest reliability, and clinical validity. It is suitable for use in daily practice and in research projects as it is able to assess patients' perception of their voice disorder severity. Copyright © 2018 The Voice Foundation.

Recent findings indicate that patients with systemic sclerosis have an increased risk of cardiovascular disease. To determine whether patients with systemic sclerosis or localized scleroderma are at increased risk of cardiovascular disease, a cohort study of the entire Danish population aged ≥ 18 and ≤ 100 years was conducted, followed from 1997 to 2011 by individual-level linkage of nationwide registries. Multivariable adjusted Cox regression models were used to estimate the hazard ratios (HRs) for a composite cardiovascular disease endpoint. A total of 697 patients with localized scleroderma and 1,962 patients with systemic sclerosis were identified and compared with 5,428,380 people in the reference population. In systemic sclerosis, the adjusted HR was 2.22 (95% confidence interval 1.99-2.48). No association was seen between patients with localized scleroderma and cardiovascular disease. In conclusion, systemic sclerosis is a significant cardiovascular disease risk factor, while patients with localized scleroderma are not at increased risk of cardiovascular disease.

Night shift work has been associated with poor sleep, weight gain, metabolic syndrome, which are recognised risk factor for diabetes. However, only a few studies have examined the effect of shift work on diabetes risk. Here, we study the association between shift work and incidence of diabetes in Danish nurses. We used the Danish Nurse Cohort with 28,731 participating female nurses recruited in 1993 (19,898) or 1999 (8833), when self-reported baseline information on diabetes prevalence, lifestyle and working time were collected, and followed them in the Danish Diabetes Register for incidence of diabetes until 2013. Nurses reported whether they worked night, evening, rotating or day shifts. We analysed the association between working time and diabetes incidence using a Cox proportional hazards model adjusted for diabetes risk factors, separately with and without adjustment for body mass index (BMI) which might be an intermediate variable. Of 19,873 nurses who worked and were diabetes-free at recruitment, 837 (4.4%) developed diabetes during 15 years of follow-up. The majority of nurses (62.4%) worked day shifts, 21.8% rotating shift, 10.1% evening and 5.5% night shifts. Compared with nurses who worked day shifts, we found statistically significantly increased risk of diabetes in nurses who worked night (1.58; 1.25 to 1.99) or evening shifts (1.29; 1.04 to 1.59) in the fully adjusted models including BMI. Danish nurses working night and evening shifts have increased risk for diabetes, with the highest risk associated with current night shift work. Published by the BMJ Publishing Group Limited.

This study validates consensus criteria for localisation of ulnar neuropathy at elbow (UNE) developed by a taskforce of the Danish Society of Clinical Neurophysiology and compares them to the existing criteria from the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM). The Danish criteria are based on combinations of conduction slowing in the segments of the elbow and forearm expressed in Z-scores, and difference between the segments in m/s. Examining fibres to several muscles and sensory fibres can increase the certainty of the localisation. Diagnostic accuracy for UNE was evaluated on 181 neurophysiological studies of the ulnar nerve from 171 peer-reviewed patients from a mixed patient-group. The diagnostic reference standard was the consensus diagnosis based on all available clinical, laboratory, and electrodiagnostic information reached by a group of experienced Danish neurophysiologists. The Danish criteria had high specificity (98.4%) and positive predictive value (PPV) (95.2%) and fair sensitivity (76.9%). Compared to the AANEM criteria, the Danish criteria had higher specificity (p<0.001) and lower sensitivity (p=0.02). The Danish consensus criteria for UNE are very specific and have high PPV. The Danish criteria for UNE are reliable and well suited for use in different centres as they are based on Z-scores. Copyright © 2017 International Federation of Clinical Neurophysiology.

The Danish study of Functional Disorders (DanFunD) cohort was initiated to outline the epidemiology of functional somatic syndromes (FSS) and is the first larger coordinated epidemiological study focusing exclusively on FSS. FSS are prevalent in all medical settings and can be defined as syndromes that, after appropriate medical assessment, cannot be explained in terms of a conventional medical or surgical disease. FSS are frequent and the clinical importance varies from vague symptoms to extreme disability. No well-described medical explanations exist for FSS, and how to delimit FSS remains a controversial topic. The specific aims with the cohort were to test delimitations of FSS, estimate prevalence and incidence rates, identify risk factors, delimitate the pathogenic pathways, and explore the consequences of FSS. The study population comprises a random sample of 9,656 men and women aged 18–76 years from the general population examined from 2011 to 2015. The survey comprises screening questionnaires for five types of FSS, ie, fibromyalgia, whiplash-associated disorder, multiple chemical sensitivity, irritable bowel syndrome, and chronic fatigue syndrome, and for the unifying diagnostic category of bodily distress syndrome. Additional data included a telephone-based diagnostic interview assessment for FSS, questionnaires on physical and mental health, personality traits, lifestyle, use of health care services and social factors, and a physical examination with measures of cardiorespiratory and morphological fitness, metabolic fitness, neck mobility, heart rate variability, and pain sensitivity. A biobank including serum, plasma, urine, DNA, and microbiome has been established, and central registry data from both responders and nonresponders are similarly available on morbidity, mortality, reimbursement of medicine, heath care use, and social factors. A complete 5-year follow-up is scheduled to take place from year 2017 to 2020, and further reexaminations will be

Prevalence of sunburn and sun-related behaviour in the Danish population: a cross-sectional study.

2010-07-01

In Denmark, the incidence of melanoma has been increasing since the 1960s. Intermittent exposure to ultraviolet radiation and a history of sunburn and sunbed use are known risk factors. We describe the association between use of protective measures, sun-related behaviour and experience of sunburn in the Danish population three months after the start of the campaign. A population-based sample of 3,499 persons aged 15-59 years completed a questionnaire that included items on exposure to ultraviolet radiation. We examined the relations between sunburn and sun-related behaviour by logistic regression analysis. Within the previous 12 months, 35% of the study population had experienced sunburn. Sunburn became less frequent with age (odds ratio (OR) 4.44; 15-19 vs. 50-59) and skin type (OR 2.57; I vs. III). Sunburn was negatively associated with shade and clothing and positively with use of sunscreens. We found no significant difference in sunscreen use between intentional tanners who experienced sunburn and those who did not. A larger fraction of unintentional tanners with sunburn than those who were not sunburnt had used sunscreen. Sunscreen was used to prolong the time spent in the sun by 66% of sunburnt people; however, we found no association between duration of sun exposure and sunscreen use. Future campaigns to reduce the prevalence of sunburn in the Danish population must especially target young persons and intentional tanning, and they should emphasize that sunscreen cannot be used to extend the time spent in the sun and that shade and clothing provide the best protection against sunburn.

The Danish Microbiology Database (MiBa) is a national database that receives copies of reports from all Danish departments of clinical microbiology. The database was launched in order to provide healthcare personnel with nationwide access to microbiology reports and to enable real-time surveillance of communicable diseases and microorganisms. The establishment and management of MiBa has been a collaborative process among stakeholders, and the present paper summarises lessons learned from this nationwide endeavour which may be relevant to similar projects in the rapidly changing landscape of health informatics.

Purpose To investigate the twin testosterone transfer (TTT) hypothesis by comparing early-life mortality risks of opposite-sex (OS) and same-sex (SS) twins during the first 15 years of life. Methods We performed a population-based cohort study to compare mortality in OS and SS twins. We included 68,629 live-born Danish twins from 1973 to 2009 identified through the Danish Twin Registry and performed piecewise stratified Cox regression and log-binomial regression. Results Among 1933 deaths, we found significantly higher mortality for twin boys than for twin girls. For both sexes, OS twins had lower mortality than SS twins; the difference persisted for the first year of life for boys and for the first week of life for girls. Conclusions Although the mortality risk for OS boys was in the expected direction according to the TTT hypothesis, the results for OS girls pointed in the opposite direction, providing no clear evidence for the TTT hypothesis.

A Danish cohort from 1987 consisting of 226 stainless steel welders and reference persons is part of the European Study Group on Cytogenetic Biomarkers and Health (ESCH). In ESCH increased cancer morbidity and mortality was significantly associated with high levels of chromosomal aberrations, measured in blood samples several years prior to cancer registration. The positive association was found in two cohorts from the Nordic countries and from Italy. ESCH followed all registered cancer cases and control persons by questionnaires and interviews to obtain information about exposures in the period from the time of blood sampling for chromosomal aberration analysis to the time of cancer diagnosis. In Denmark the total cohort was included in the inquiry and the ESCH questions were supplemented with questions from the Danish National Work Environment Cohort Study 1990-95. Responses from one hundred and forty-four persons showed that seventy-four were employed at the same workplace place as in 1987. Differences in occupational exposures, such as more noise, heat and insufficient lighting and no differences in the self-rated health were found in comparison with the Danish National Work Environment Cohort Study as such and with the sample of metal workers. Only very few of the study persons knew the threshold limit value of welding fumes but a majority found that the working environment had improved during the past ten years. This study confirms hazardous exposures in stainless steel welding. The threshold limit value, however, has been lowered since 1987 suggesting there is less cancer risk today from stainless steel welding.

We aimed to determine the incidence rate and time trend of approved treatment injuries in Danish public hospitals from 2006 to 2012 and also to identify independent predictors of severe treatment injuries among patient and system factors and characterize the injuries. We performed a nationwide, historical observational study on data from the Danish Patient Compensation Association, which receives all compensation claims from Danish health care. All approved closed claims of treatment injuries occurring in public hospitals 2006-12 were included. Health care activity information was obtained through Statistics Denmark. Incidence rates were determined as treatment injuries per year by population and by public hospital contacts. By using a multivariable logistic regression model, we calculated mutually adjusted odds ratios to assess the association between potential predictors and severe injuries among approved claims. We identified 10,959 approved treatment injury claims in 2006-12. The total payout was USD 339 million. The mean incidence rate medians were 27.9 injuries/100,000 inhabitants/year and 0.21 injuries/1000 public hospital contacts/year. These did not increase overtime. Severe injuries and preventable cases comprised 11.0 and 41.0%, respectively. Predictors of severe injury included age 0 and above 40 years, male gender and higher level of comorbidity. The incidence rate of approved closed claims at Danish public hospitals appears stable. A high proportion of injuries are preventable and both patient- and system-related factors may predict severe injuries. © The Author 2015.

The aim of this paper is to describe the design and methods used in the Danish Youth Cohort and to give a description of the study participants with special attention to a comparison between participants and non-participants regarding sociodemographic characteristics. A total of 1,945 schools were invited, out of which 506 participated. The participating 7th grades comprised a total of 12,498 responding adolescents. The response rate for the Danish Youth Cohort established in 2005 was 63%. The sample of 12,498 adolescents represents 18.2% of all pupils (n = 68,764) in the 7th grade (mean age: 13.4 years) in Danish schools in 2005. The cohort was followed up in spring 2006 and spring 2007, where the adolescents were in the 8th (mean age: 14.4 years) and 9th (mean age: 15.3 years) grades, respectively. We found that compared with non-participants the participants were significantly more likely to be girls, to be of Danish ethnicity, and to live in one-family houses. Furthermore, participants more often came from families with two or three children, were more likely to have parents with a high occupational status, parents who were married and parents with a higher total income. Loss to follow-up was only associated with adolescents' higher probability of drinking and use of tobacco, and none of the other factors were associated with attrition. The participants in the Danish Youth Cohort represent a great variety of different groups of socio-demographic factors, although they differ from non-participants as regards a range of socio-demographic factors. This should be taken into account in future analyses.

The aim of this paper was to estimate the effect of maternal and paternal smoking on foetal death (miscarriage and stillbirth) and to estimate potential interactions with physical exercise and pre-pregnancy body mass index. We selected 87,930 pregnancies from the population-based Danish National Birth Cohort. Information about lifestyle, occupational, medical and obstetric factors was obtained from a telephone interview and data on pregnancy outcomes came from the Danish population based registries. Cox regression was used to estimate the hazard ratios (adjusted for potential confounders) for predominantly late foetal death (miscarriage and stillbirth). An interaction contrast ratio was used to assess potential effect measure modification of smoking by physical exercise and body mass index. The adjusted hazard ratio of foetal death was 1.22 (95 % CI 1.02-1.46) for couples where both parents smoked compared to non-smoking parents (miscarriage: 1.18, 95 % CI 0.96-1.44; stillbirth: 1.32, 95 % CI 0.93-1.89). On the additive scale, we detected a small positive interaction for stillbirth between smoking and body mass index (overweight women). In conclusion, smoking during pregnancy was associated with a slightly higher hazard ratio for foetal death if both parents smoked. This study suggests that smoking may increase the negative effect of a high BMI on foetal death, but results were not statistically significant for the interaction between smoking and physical exercise.

Death by Suicide in Graves' Disease and Graves' Orbitopathy: A Nationwide Danish Register Study.

2017-12-01

Graves' disease (GD) is associated with excess morbidity and mortality, but little is known about unnatural manners of death and the potential relation with Graves' orbitopathy (GO). This study investigated the risk of unnatural death in Graves' patients with and without orbitopathy compared to matched control populations. This was a cohort study covering all adult Danes (≥18 years) diagnosed with GD or GO during 1995-2012. Median follow-up time was 7.9 years (range 0-17.5 years). Utilizing the Danish Register of Causes of Death and the Danish National Patient Registry, 28,461 subjects with GD and 3965 with GO were identified and matched for age and sex with four subjects from the background population. The manner of death was identified, and hazard ratios (HR) for mortality due to unnatural deaths (accident, suicide, violence/homicide, and unknown) were calculated using Cox regression analyses, adjusted for pre-existing somatic and psychiatric morbidity. In Graves' disease overall (GD + GO), there was an increased risk of death from unknown unnatural manners (HR = 2.01 [confidence interval (CI) 1.17-3.45], p = 0.012) and of suicide, although the latter difference was not with certainty statistically significant (HR = 1.43 [CI 1.00-2.04], p = 0.053). There was no significant difference in risk of death from suicide in GD subjects compared to their controls (HR = 1.27 [CI 0.85-1.89], p = 0.253). However, GO patients had a significantly higher risk of death from suicide (HR = 2.71 [CI 1.16-6.32], p = 0.022). Mortality by suicide was increased in Graves' disease overall, most significantly in patients with GO, also after adjustment for pre-existing somatic and psychiatric disease. These findings indicate that GD and GO may have a significant role in the pathophysiological mechanisms of suicidal behavior. Beyond independent confirmation, reasons for this need to be explored in order to introduce preventive measures.

We aimed to assess the risk of death, cancer, and comorbidities among patients with alcoholic and nonalcoholic chronic pancreatitis (CP). We performed a nationwide retrospective cohort study, collecting data from Danish registries from 1995 through 2010. We evaluated the prevalences and incidences of death, cancers, and comorbidities among subjects with CP (cases) compared with age- and sex-matched individuals (controls). In total, 11,972 cases (71,814 person-years) and 119,720 controls (917,436 person-years) were included in the analysis. Hazard ratios (HR) were estimated by Cox proportional hazards regression. Forty-six percent of the cases died during the follow-up period, compared with 13.0% of controls (mean age, 63.7 vs 72.1 y; P < .0001), corresponding to a HR of 5.0 for CP (95% confidence interval [CI], 4.8-5.2). Cancer was a frequent cause of death among cases (10.2%) and controls (3.3%). Cancer (particularly pancreatic cancer) was a frequent cause of death among cases; the HR was 6.9 (95% CI, 7.5-11.8). Alcoholic CP did not produce a higher risk for cancer or death than nonalcoholic CP. Cerebrovascular disease (HR, 1.3; 95% CI, 1.2-1.4), chronic pulmonary disease (HR, 1.9; 95% CI, 1.8-2.1), ulcer disease (HR, 3.6; 95% CI, 3.3-3.9), diabetes (HR, 5.2; 95% CI, 5.0-5.6), and chronic renal disease (HR, 1.7; 95% CI, 1.5-1.9) occurred more frequently among patients with CP, but myocardial infarction did not (HR, 0.9; 95% CI, 0.8-1.0). Based on a Danish nationwide cohort study, individuals with CP are at higher risk for death from cancer (particularly pancreatic cancer) and have a higher incidence of comorbidities than people without CP.

The aim of this study was to investigate whether consumption of coffee, tea and caffeine affects the risk of primary infertility in women. We selected nulliparous Danish women aged 20-29 years from a prospective cohort and retrieved information on coffee and tea consumption from a questionnaire and an interview at enrollment. We assessed the women's fertility by linkage to the Danish Infertility Cohort and retrieved information on children and vital status from the Civil Registration System. All 7574 women included for analysis were followed for primary infertility from the date of enrollment (1991-1993) until 31 December 2010. Analyses were performed with Cox proportional hazard models. During follow up, primary infertility was diagnosed in 822 women. Compared with never consumers, the risk of primary infertility among women who drank coffee or tea was not affected. The risk of primary infertility was neither associated with an increasing number of daily servings of coffee (hazard ratio 1.00; 95% confidence interval (CI), 0.97-1.03) or tea (hazard ratio 1.01; 95% CI, 0.99-1.03) in consumers only. Concerning total caffeine consumption (from coffee and tea), the risk of infertility was similar among consumers compared with never consumers. Finally, none of the additional daily 100 mg of caffeine affected the risk among consumers only (hazard ratio 1.00; 95% CI 0.98-1.02). In this population-based cohort study, not restricted to women seeking pregnancy, we found no association between coffee, tea or total caffeine consumption and the risk of primary infertility in women. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

Posttraumatic pituitary hormone deficiency is often suggested. The impact of these predominantly mild and often irreproducible deficiencies on outcome is less clear. The aim of the present study was to describe patient reported outcome in a national a priori unselected cohort of patients with traumatic brain injury (TBI) in relation to deficiencies identified upon pituitary assessment. We conducted a nationwide population-based cohort study. Participants were Danish patients with a head trauma diagnosis recorded in the Danish Board of Health diagnostic code registry; 439 patients (and 124 healthy controls) underwent assessment of anterior pituitary function 2.5 years (median) after TBI. Questionnaires on health-related quality of life (QoL) (SF36, EuroQoL-5D, QoL assessment of GH deficiency in adults) and fatigue (MFI-20) were completed in parallel to pituitary assessment. Patients with TBI had significant detriments in QoL. Impairment (mainly physical scales) related to pituitary deficiency, although only partially confirmed after adjustment for demographic differences. Hypogonadotropic hypogonadism related to several QoL scores. Increasing impairments were observed with declining total testosterone concentrations (men), but not free testosterone concentrations or any other hormone concentrations. Total testosterone was not independently related to impaired QoL and fatigue, after adjustment for demographics, and treatment with antidiabetics, opioids, antidepressants, and anticonvulsants. Only a very limited relationship between pituitary hormone deficiencies and QoL/fatigue was demonstrated. Due to the dominating influence of concurrent comorbidities, pituitary deficiencies were not independently related to QoL/fatigue. Causality is still to be shown, and whether substitution therapy could be of additional relevance in selected patients needs to be proven. © 2015 European Society of Endocrinology.

This cohort study was based on data from the Danish Health Examination Survey 2007-2008. Of the 76,484 survey participants, 28,704 men and 41,847 women were eligible for this study. Participants were followed for a median of 4.9 years. Self-reported questionnaires were used to obtain information on alcohol drinking patterns, i.e. frequency of alcohol drinking, frequency of binge drinking, and consumption of wine, beer and spirits, from which we calculated beverage-specific and overall average weekly alcohol intake. Information on incident cases of diabetes was obtained from the Danish National Diabetes Register. Cox proportional hazards model was applied to estimate HRs and 95% CIs. During follow-up, 859 men and 887 women developed diabetes. The lowest risk of diabetes was observed at 14 drinks/week in men (HR 0.57 [95% CI 0.47, 0.70]) and at 9 drinks/week in women (HR 0.42 [95% CI 0.35, 0.51]), relative to no alcohol intake. Compared with current alcohol consumers consuming <1 day/week, consumption of alcohol on 3-4 days weekly was associated with significantly lower risk for diabetes in men (HR 0.73 [95% CI 0.59, 0.94]) and women (HR 0.68 [95% CI 0.53, 0.88]) after adjusting for confounders and average weekly alcohol amount. Our findings suggest that alcohol drinking frequency is associated with risk of diabetes and that consumption of alcohol over 3-4 days per week is associated with the lowest risk of diabetes, even after taking average weekly alcohol consumption into account.

The Danish health system through an American lens.

Davis, Karen

The organization and financing of the Danish health care system was evaluated within the framework of a SWOT analysis (analysis of strengths, weaknesses, opportunities and threats) by a panel of five members with a background in health economics. The evaluation was based on reading an extensive amount of selected documents and literature on the Danish health care system and a 1-week visit to health care authorities, providers and key persons. The present paper includes the main findings by one of the panel members. Primary care is much more accessible in Denmark than the USA. A mixed capitation-fee-for-service method of paying generalist physicians in Denmark ensures that everyone has a primary care physician and generalist physicians are responsive to providing services quickly, typically same-day appointments. An organized off-hours service ensures accessible care 24 h a day, 7 days a week. Denmark has the highest public satisfaction with health care, reflecting the value placed on accessibility of primary care. Inpatient hospital care consumes a disproportionate share of Danish health expenditures. Global hospital budgets provide little incentive for hospital or surgical productivity. Long waits for hospitalization, especially surgical procedures and cancellation of scheduled surgery, are a source of patient dissatisfaction. Women's health, patient health risk counseling and coordination of preventive and primary care are major weaknesses of the Danish health system. Patients have a choice of primary care physician within a given geographic area and may go to a hospital of their choice. However, patient surveys and feedback are underdeveloped and very little effort has been made to make services responsive to patients' preferences. While innovations in electronic prescribing are noteworthy, further development of health information technology is needed.

Theorising EIA effectiveness: A contribution based on the Danish system

Lyhne, Ivar, E-mail: lyhne@plan.aau.dk; Laerhoven, Frank van; Cashmore, Matthew

Considerable attention has been given to the effectiveness of environmental impact assessment (EIA) since the 1970s. Relatively few research studies, however, have approached EIA as an instrument of environmental governance, and have explored the mechanisms through which EIA influences the behaviour of actors involved in planning processes. Consequently, theory in this area is underspecified. In this paper we contribute to theory-building by analysing the effectiveness of a unique EIA system: the Danish system. In this system the competent authority, instead of the project proponent, undertakes EIA reporting. Additionally, the public, rather than experts, play a central role in quality controlmore » and the Danish EIA community is relatively small which influences community dynamics in particular ways. A nation-wide survey and expert interviews were undertaken in order to examine the views of actors involved in EIA on the effectiveness of this anomalous system. The empirical data are compared with similar studies on governance mechanisms in other countries, especially the United Kingdom and the Netherlands, as well as with earlier evaluations of EIA effectiveness in Denmark. The results indicate that the more extensive role attributed to the competent authority may lead to higher EIA effectiveness when this aligns with their interests; the influence of the public is amplified by a powerful complaints system; and, the size of the EIA community appears to have no substantial influence on EIA effectiveness. We discuss how the research findings might enhance our theoretical understanding of the operation and effectiveness of governance mechanisms in EIA. - Highlights: • The effectiveness of the unique Danish EIA system is explored. • Results are compared with similar studies in the Netherlands and the UK. • Findings lead to hypotheses that contribute to theorising EIA effectiveness.« less

Danish dementia mice suggest that loss of function and not the amyloid cascade causes synaptic plasticity and memory deficits

According to the prevailing “amyloid cascade hypothesis,” genetic dementias such as Alzheimer’s disease and familial Danish dementia (FDD) are caused by amyloid deposits that trigger tauopathy, neurodegeneration, and behavioral/cognitive alterations. To efficiently reproduce amyloid lesions, murine models of human dementias invariably use transgenic expression systems. However, recent FDD transgenic models showed that Danish amyloidosis does not cause memory defects, suggesting that other mechanisms cause Danish dementia. We studied an animal knock-in model of FDD (FDDKI/+) genetically congruous with human cases. FDDKI/+ mice present reduced Bri2 levels, impaired synaptic plasticity and severe hippocampal memory deficits. These animals show no cerebral lesions that are reputed characteristics of human dementia, such as tangles or amyloid plaques. Bri2+/− mice exhibit synaptic and memory deficits similar to FDDKI/+ mice, and memory loss of FDDKI/+ mice is prevented by expression of WT BRI2, indicating that Danish dementia is caused by loss of BRI2 function. Together, the data suggest that clinical dementia in Danish patients occurs via a loss of function mechanism and not as a result of amyloidosis and tauopathy. PMID:21098268

Background We were unable to identify studies that have considered the diffusion of an e-learning programme among a large population of general practitioners. The aim of this study was to investigate the uptake of an e-learning programme introduced to General Practitioners as part of a nation-wide disseminated dementia guideline. Methods A prospective study among all 3632 Danish GPs. The GPs were followed from the launching of the e-learning programme in November 2006 and 6 months forward. Main outcome measures: Use of the e-learning programme. A logistic regression model (GEE) was used to identify predictors for use of the e-learning programme. Results In the study period, a total of 192 different GPs (5.3%) were identified as users, and 17% (32) had at least one re-logon. Among responders at first login most have learnt about the e-learning programme from written material (41%) or from the internet (44%). A total of 94% of the users described their ability of conducting a diagnostic evaluation as good or excellent. Most of the respondents used the e-learning programme due to general interest (90%). Predictors for using the e-learning programme were Males (OR = 1.4, 95% CI 1.1; 2.0) and members of Danish College of General Practice (OR = 2.2, 95% CI 1.5; 3.1), whereas age, experience and working place did not seem to be influential. Conclusion Only few Danish GPs used the e-learning programme in the first 6 months after the launching. Those using it were more often males and members of Danish College of General Practice. Based on this study we conclude, that an active implementation is needed, also when considering electronic formats of CME like e-learning.

The aim of the present study was to provide a broad picture of the morbidity among employees in the Danish hotel and restaurant industry. Cohorts of all 20-59-year-old employees in the Danish hotel and restaurant industry in the years 1981, 1986, 1991 and 1994 were formed to calculate age-standardized hospitalization ratios (SHR) and time trends (1981-1997) for many different diagnoses. Both for women and men, significantly higher SHRs were found for infectious and parasitic diseases, neoplasms, diseases in the nervous system and sense organs, diseases of the circulatory system, diseases of the respiratory system, diseases of the digestive system and diseases of the musculoskeletal system among employees in hotels and restaurants than in the digestive system and diseases of the musculoskeletal system among employees in hotels and restaurants than in the working population at large. Furthermore, among women a significantly elevated risk was found for injuries in the lower extremities, injuries in the upper extremities and head injuries, and among men a high risk was found for head injuries and a low risk for ruptures in ligaments and muscles. The trend assessments did not detect any significant changes in SHRs over time. Employment in the Danish hotel and restaurant industry is associated with an elevated hospitalization risk due to many diseases, which may be related to occupation and lifestyle. In line with the official policy of reducing inequality in health, focus should be placed on the health problems in this group.

Myeloproliferative neoplasms (MPNs) are a heterogeneous group of diseases characterized by clonal hyperproliferation of immature and mature cells of the myeloid lineage. Genetic differences have been proposed to play a role in the development of MPNs. Monozygotic twin pairs with MPNs have been reported in a few case reports, but the MPN concordance pattern in twins remains unknown. All twin pairs born in the period 1900-2010 were identified in the nationwide Danish Twin Registry. Only pairs with both twins alive on January 1, 1977, and those born thereafter were included to allow identification in the Danish National Patient Registry. A total of 158 twin pairs were registered with an MPN diagnosis: 36 monozygotic, 104 dizygotic, and 18 pairs with unknown zygosity. MPNs were diagnosed in both twins in 4 pairs. The probandwise concordance rates for monozygotic twin pairs were higher than for dizygotic twin pairs (15 vs. 0%; p = 0.016). An estimated concordance rate of 15% (95% CI 0.059-0.31) is modest, but given the rarity of MPNs this finding is clinically relevant and provides further support for the role of genetic predisposition in the development of MPNs. © 2018 S.

Danish A.I. field data with sexed semen.

PubMed

Borchersen, S; Peacock, M

2009-01-01

The objective of this study was to compare conception rates, non-return rates and sex ratios of sexed and conventional semen from the same sires in commercial dairy herds in Denmark. The semen was produced from three bulls from each of the three major dairy breeds in Denmark: Holstein, Jersey and Danish Red Dairy Breed (nine bulls total), in order to answer questions on breeds differences in field results. AI was performed by trained technicians using a minimum of 150 doses of sorted sperm and 50 control doses from each bull. During the trial, a total of 2087 doses were used in 63 herds. The trial showed that the conception rate using sorted semen was 5% points lower than with conventional doses for Danish Reds, 7% points for Jerseys, and 12% points for Holsteins. Translating this into non-return rate revealed differences of 10-20% points among bulls. These differences are thought to be a good indicator of what to expect from commercial use of sexed semen. The sex ratios varied from 89% to 93% female calves among breeds, which on average is consistent with the theoretical average sex ratio of 93% females considering the low number of inseminations.

Objective The rate of change in metabolic phenotypes can be highly indicative of metabolic disorders and disorder-related modifications. We analyzed data from longitudinal twin studies on multiple metabolic phenotypes in Danish and Chinese twins representing two populations of distinct ethnic, cultural, social-economic backgrounds and geographical environments. Materials and Methods The study covered a relatively large sample of 502 pairs of Danish adult twins followed up for a long period of 12 years with a mean age at intake of 38 years (range: 18–65) and a total of 181 Chinese adult twin pairs traced for about 7 years with a mean baseline age of 39.5 years (range: 23–64). The classical twin models were fitted to the longitudinal change in each phenotype (Δphenotype) to estimate the genetic and environmental contributions to the variation in Δphenotype. Results Moderate to high contributions by the unique environment were estimated for all phenotypes in both Danish (from 0.51 for low density lipoprotein cholesterol up to 0.72 for triglycerides) and Chinese (from 0.41 for triglycerides up to 0.73 for diastolic blood pressure) twins; low to moderate genetic components were estimated for long-term change in most of the phenotypes in Danish twins except for triglycerides and hip circumference. Compared with Danish twins, the Chinese twins tended to have higher genetic control over the longitudinal changes in lipids (except high density lipoprotein cholesterol) and glucose, higher unique environmental contribution to blood pressure but no genetic contribution to longitudinal change in body mass traits. Conclusion Our results emphasize the major contribution of unique environment to the observed intra-individual variation in all metabolic phenotypes in both samples, and meanwhile reveal differential patterns of genetic and common environmental regulation on changes over time in metabolic phenotypes across the two samples.

The aim of the database, which has existed for registration of all patients with colorectal cancer in Denmark since 2001, is to improve the prognosis for this patient group. All Danish patients with newly diagnosed colorectal cancer who are either diagnosed or treated in a surgical department of a public Danish hospital. The database comprises an array of surgical, radiological, oncological, and pathological variables. The surgeons record data such as diagnostics performed, including type and results of radiological examinations, lifestyle factors, comorbidity and performance, treatment including the surgical procedure, urgency of surgery, and intra- and postoperative complications within 30 days after surgery. The pathologists record data such as tumor type, number of lymph nodes and metastatic lymph nodes, surgical margin status, and other pathological risk factors. The database has had >95% completeness in including patients with colorectal adenocarcinoma with >54,000 patients registered so far with approximately one-third rectal cancers and two-third colon cancers and an overrepresentation of men among rectal cancer patients. The stage distribution has been more or less constant until 2014 with a tendency toward a lower rate of stage IV and higher rate of stage I after introduction of the national screening program in 2014. The 30-day mortality rate after elective surgery has been reduced from >7% in 2001-2003 to <2% since 2013. The database is a national population-based clinical database with high patient and data completeness for the perioperative period. The resolution of data is high for description of the patient at the time of diagnosis, including comorbidities, and for characterizing diagnosis, surgical interventions, and short-term outcomes. The database does not have high-resolution oncological data and does not register recurrences after primary surgery. The Danish Colorectal Cancer Group provides high-quality data and has been documenting an

The objective of this study was to examine the psychometric properties of the Danish version of the Barriers Questionnaire-II (DBQ-II). The validated Norwegian version of the DBQ-II was translated into Danish. Cancer patients for the study were recruited from specialized pain management facilities. Thirty-three patients responded to the DBQ-II, Hospital Anxiety and Depression Scale, and Brief Pain Inventory pain severity scale. A factor analysis of the DBQ-II resulted in six scales. Scale one, Fatalism, consisted of three items addressing fatalistic beliefs regarding cancer pain management. Scale two, Immune System, consisted of three items addressing the belief that pain medications harm the immune system. Scale three, Monitor, consisted of three items addressing the fear that pain medicine masks changes in one's body. Scale four, Communication, consisted of five items addressing the concern that reports of pain distract the physician from treating the cancer, and the belief that "good" patients do not complain. Scale five, Addiction, consisted of two items addressing the fear of becoming addicted to pain medication. Finally, scale six, Tolerance, consisted of three items addressing the fear of getting tolerant to analgesic effect of pain medicine. Items related to medication side effects were analyzed as separate units. The DBQ-II total had an internal consistency of 0.87. The DBQ-II total score was related to measures of pain relief and anxiety. The DBQ-II seems to be a reliable and valid measure of the barriers to pain management among Danish cancer patients.

Immunological changes in and after a pregnancy may influence the onset of autoimmune diseases. An increased incidence of hyperthyroidism has been observed both in early pregnancy and postpartum, but it remains to be studied if the incidence of hypothyroidism varies in a similar way. Population-based cohort study using Danish nationwide registers. All women who gave birth to a singleton live-born child in Denmark from 1999 to 2008 (n = 403 958) were identified, and data on hospital diagnosis of hypothyroidism and redeemed prescriptions of thyroid hormone were extracted. The overall incidence rate (IR) of hypothyroidism during 1997-2010 and the IR in three-month intervals before, during and after the woman's first pregnancy in the study period were calculated and compared with the IR of hyperthyroidism. Altogether 5220 women were identified with onset of hypothyroidism from 1997 to 2010 (overall IR 92.3/100 000/year) and 1572 women developed hypothyroidism in the period from 2 years before to 2 years after birth of the first child in the study period. The incidence of hypothyroidism decreased during the pregnancy (incidence rate ratio (IRR) vs overall IR in the rest of the study period: first trimester: 0.89 (95% CI: 0.66-1.19), second trimester: 0.71 (0.52-0.97), third trimester: 0.29 (0.19-0.45)) and increased after birth with the highest level at 4-6 months postpartum (IRR 3.62 (2.85-4.60)). These are the first population-based data on the incidence of hypothyroidism in and around pregnancy. The incidence declined during pregnancy followed by a sharp increase postpartum. Notably, hypothyroidism as opposed to hyperthyroidism showed no early pregnancy increase. © 2016 European Society of Endocrinology.

Evaluation of Three Models for Simulating Pesticide Runoff from Irrigated Agricultural Fields.

PubMed

Zhang, Xuyang; Goh, Kean S

2015-11-01

Three models were evaluated for their accuracy in simulating pesticide runoff at the edge of agricultural fields: Pesticide Root Zone Model (PRZM), Root Zone Water Quality Model (RZWQM), and OpusCZ. Modeling results on runoff volume, sediment erosion, and pesticide loss were compared with measurements taken from field studies. Models were also compared on their theoretical foundations and ease of use. For runoff events generated by sprinkler irrigation and rainfall, all models performed equally well with small errors in simulating water, sediment, and pesticide runoff. The mean absolute percentage errors (MAPEs) were between 3 and 161%. For flood irrigation, OpusCZ simulated runoff and pesticide mass with the highest accuracy, followed by RZWQM and PRZM, likely owning to its unique hydrological algorithm for runoff simulations during flood irrigation. Simulation results from cold model runs by OpusCZ and RZWQM using measured values for model inputs matched closely to the observed values. The MAPE ranged from 28 to 384 and 42 to 168% for OpusCZ and RZWQM, respectively. These satisfactory model outputs showed the models' abilities in mimicking reality. Theoretical evaluations indicated that OpusCZ and RZWQM use mechanistic approaches for hydrology simulation, output data on a subdaily time-step, and were able to simulate management practices and subsurface flow via tile drainage. In contrast, PRZM operates at daily time-step and simulates surface runoff using the USDA Soil Conservation Service's curve number method. Among the three models, OpusCZ and RZWQM were suitable for simulating pesticide runoff in semiarid areas where agriculture is heavily dependent on irrigation.

Compared with controls, up to six years after their return, Danish Gulf War Veterans have a significantly higher prevalence of self-reported neuropsychological symptoms. Independent associations are found for concentration or memory problems, repeated fits of headache, balance disturbances or fits of dizziness, abnormal fatigue not caused by physical activity, and problems sleeping all night. We investigated whether psychosocial, physical, chemical or biological exposures were associated with these symptoms. This study is a prevalence study using retrospective data on exposure. Some 686 subjects who had been deployed in the Persian Gulf within the period August 2 1990 until December 31 1997 were included; the control group comprised 257 subjects matched according to age, gender and profession. All participants underwent clinical and paraclinical examinations, and were interviewed by a physician based on a completed questionnaire. A clustering of three to five of the above symptoms were found in 21.4% of Gulf War Veterans vs. 6.2% in controls, p < 0.001. Psychosocial and physico-chemical factors were strongly associated with neuropsychological symptoms, and a significant interaction of the two was found, p < 0.001. Although the results of this study are based on self-report the factors identified seem plausible. It may be impossible even in peace-keeping missions to avoid hostile events. However, the results also suggest that psychosocial work conditions known to be important in civilian life, and also environmental factors, should be improved to minimize the risk of long-term neuropsychological symptoms.

Mortality rates in complicated peptic ulcer disease are high. This study aimed to examine the prognostic importance of ulcer site in patients with peptic ulcer bleeding (PUB) and perforated peptic ulcer (PPU). a nationwide cohort study with prospective and consecutive data collection. all patients treated for PUB and PPU at Danish hospitals between 2003 and 2014. demographic and clinical data reported to the Danish Clinical Registry of Emergency Surgery. 90- and 30-d mortality and re-intervention. the crude and adjusted association between ulcer site (gastric and duodenal) and the outcome measures of interest were assessed by binary logistic regression analysis. Some 20,059 patients with PUB and 4273 patients with PPU were included; 90-d mortality was 15.3% for PUB and 29.8% for PPU; 30-d mortality was 10.2% and 24.7%, respectively. Duodenal bleeding ulcer, as compared to gastric ulcer (GU), was associated with a significantly increased risk of all-cause mortality within 90 and 30 d, and with re-intervention: adjusted odds ratio (OR) 1.47 (95% confidence interval 1.30-1.67); p < 0.001, OR 1.60 (1.43-1.77); p < 0.001, and OR 1.86 (1.68-2.06); p < 0.001, respectively. There was no difference in outcomes between gastric and duodenal ulcers (DUs) in PPU patients: adjusted OR 0.99 (0.84-1.16); p = 0.698, OR 0.93 (0.78 to 1.10); p = 0.409, and OR 0.97 (0.80-1.19); p = 0.799, respectively. DU site is a significant predictor of death and re-intervention in patients with PUB, as compared to GU site. This does not seem to be the case for patients with PPU.

The effect of an implantable cardioverter defibrillator (ICD) in patients with symptomatic systolic heart failure (HF) caused by coronary artery disease is well documented. However, the effect of primary prophylactic ICDs in patients with systolic HF not due to coronary artery disease is much weaker. In addition, HF management has improved, since the landmark ICD trials and a large proportion of patients now receive cardiac resynchronization therapy (CRT) where the effect of ICD treatment is unknown. In the DANISH study, 1,116 patients with symptomatic systolic HF not caused by coronary artery disease have been randomized to receive an ICD or not, in addition to contemporary standard therapy. The primary outcome of the trial is time to all-cause death. Follow-up will continue until June 2016 with a median follow-up period of 5 years. Baseline characteristics show that enrolled patients are treated according to current guidelines. At baseline, 97% of patients received an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, 92% received a β-blocker, 58% a mineralocorticoid receptor antagonist, and 58% were scheduled to receive CRT. Median age was 63 years (range, 21-84 years) at baseline, and 28% were women. DANISH will provide pertinent information about the effect on all-cause mortality of a primary prophylactic ICD in patients with symptomatic systolic HF not caused by coronary artery disease on contemporary standard therapy including CRT.

The objective of the study was to examine the educational exposure during residency in Danish orthopedic departments. Questionnaire-based cross-sectional study. Data were gathered from January 1, 2014 to April 30, 2014 through a nationwide web-based questionnaire containing 15 questions within the areas of workload, surgical procedures, outpatient clinic, and research activities. The residents targeted worked at small-to-large hospitals and in tertiary care centers. Every resident in Denmark (n = 163) with at least 3 active months at a department was included. Questionnaires with less than 80% completion were excluded. In total, 152 entries were registered. Among those, 27 did not meet the inclusion criteria and 29 were excluded, leaving 96 participants, representing 22 of 26 departments, for further analysis. The average number of operative procedures as primary surgeon was 16 (range: 8-35) per month. In all, 18 of 22 (81%) departments offered the possibility to participate in research facilitated by the department and 38 of 96 (40%) worked for free (an average of 10h a month [range: 3-60]) to increase the amount of surgical procedures. A large variation in the educational exposure was found among the Danish orthopedic departments. Numbers indicate that Danish residents, compared with their US counterparts, operate considerably less during residency. Most residents work overtime and many of them work for free to participate in more surgical procedures. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

Janssen, Richard

2002-02-01

The organization and financing of the Danish health care system was evaluated within a framework of a SWOT analysis (analysis of strengths, weaknesses, opportunities and threats) by a panel of five members with a background in health economics. The evaluation was based on the reading of an extensive range of documents and literature on the Danish health care system, and a 1-week visit to health care authorities, providers and key persons. The present paper describes the main findings of one of the panel members. A quality assessment approach is combined with the principles of a SWOT analysis to assess the main features of the Danish health care system. In addition, a public health perspective has been used in judging the coherence of the subsystems of the health systems. It is concluded that the macro-efficiency of the health care system could be increased by improving the cooperation between the subsystems. The relatively high mortality rates suggest that greater input into health education programs could significantly improve the health status of the Danish population. Finally, it is suggested that the steering power of the public board be strengthened by transferring ownership of health care institutions to other hands (privatization).

It is possible that reduced function of DNA repair and cell-cycle control genes increases the individual susceptibility to malignant melanoma. As CHEK2 is a cell-cycle master controller, we tested the hypothesis that heterozygosity for the frameshift alteration CHEK2*1100delC is associated with increased risk of malignant melanoma. First, we performed case-control studies of 1,152 Danish and 752 German individuals with malignant melanoma compared with 9,142 Danish and 3,718 German controls. Second, we performed a meta-analysis of CHEK2*1100delC and malignant melanoma, involving 2,619 cases and 17,481 controls. Third, we examined the risk of malignant melanoma associated with CHEK2*1100delC heterozygosity in an analysis stratified for sun exposure, as well as for subtype and location on the body. The odds ratios for malignant melanoma for CHEK2(*)1100del heterozygotes compared with those for noncarriers were 2.01 (95% confidence interval (CI), 1.03-3.91) in Danes, 1.42 (95% CI, 0.46-4.31) in Germans, and 1.79 (95% CI, 1.02-3.17) in Danes and Germans combined. In a meta-analysis, the odds ratio of malignant melanoma for CHEK2*1100delC heterozygotes compared with that for noncarriers was 1.81 (95% CI, 1.07-3.05). Stratifications did not alter these results. CHEK2*1100delC heterozygotes have a twofold risk of malignant melanoma compared with noncarriers.

[The Danish debate on priority setting in medicine - characteristics and results].

Priority setting in medicine helps to achieve a fair and transparent distribution of health-care resources. The German discussion about priority setting is still in its infancy and may benefit from other countries' experiences. This paper aims to analyse the Danish priority setting debate in order to stimulate the German discussion. The methods used are a literature analysis and a document analysis as well as expert interviews. The Danish debate about priority setting in medicine began in the 1970s, when a government committee was constituted to evaluate health-care priorities at the national level. In the 1980s a broader debate arose in politics, ethics, medicine and health economy. The discussions reached a climax in the 1990s, when many local activities - always involving the public - were initiated. Some Danish counties tried to implement priority setting in the daily routine of health care. The Council of Ethics was a major player in the debate of the 1990s and published a detailed statement on priority setting in 1996. With the new century the debate about priority setting seemed to have come to an end, but in 2006 the Technology Council and the Danish Regions resumed the discussion. In 2009 the Medical Association called for a broad debate in order to achieve equity among all patients. The long lasting Danish debate on priority setting has entailed only very little practical consequences on health care. The main problems seem to have been the missing effort to bundle the various local initiatives on a national level and the lack of powerful players to put results of the discussion into practice. Nevertheless, today the attitude towards priority setting is predominantly positive and even politicians talk freely about it. © Georg Thieme Verlag KG Stuttgart · New York.

Purpose Compliance with the Danish preconceptional folic acid (FA) recommendation – a daily supplement of 400 μg – is reported to be poor. Uncertainty remains, however, about the prevalence of compliers and health-related predictors of compliance in the preconceptional period. Methods We used self-reported baseline data from 5383 women, aged 18–40 years, enrolled in an Internet-based prospective cohort study of Danish pregnancy planners during 2007–2011. We estimated the prevalence proportions of FA or multivitamin (MV) use in relation to selected sociodemographic, lifestyle, reproductive, and medical characteristics. Multivariate binomial regression was used to obtain prevalence proportion differences with 95% confidence intervals for each level of study predictors, adjusted for all other predictors. Results Overall, 7.7% of women used FA supplements, 20.4% used MV supplements, 34.0% used both, 1.5% used other single vitamins or minerals, and 36.4% did not use any dietary supplements. The prevalence of FA or MV supplement use was higher among older women, women with higher education and income, and women with healthy lifestyle factors such as being a nonsmoker, nondrinker, physically active, maintaining a normal body mass index and having regular pap smears. Greater intercourse frequency and a history of spontaneous abortion were also positively associated with FA or MV supplement use. We found no clear association between use of FA or MV supplements and a diagnosis of hypertension, diabetes, thyroid disease, pelvic inflammatory disease, or chlamydia. Conclusion A large proportion of pregnancy planners do not use FA or MV supplements. Pregnancy planners with generally risky lifestyle behaviors are less likely to comply with the FA recommendation.

1992-09-01

To investigate the role of employment history and workplace exposures as risk factors for multiple myeloma among women, a population-based case-control study using the Danish Cancer Registry data linkage system was conducted. All cases of myeloma diagnosed in Danish women between 1970 and 1984 (1,010 cases) and 4,040 age-matched women alive at the time of case-diagnosis were identified. Industrial histories from 1964 forward were obtained from the nationwide Pension Fund for 363 cases and 1,517 controls, and the most recent occupation on the tax record was available for 607 cases and 2,596 controls. Using industry/occupational-code combinations for the cases and controls who had industry employment, Danish industrial hygienists assessed the likelihood of exposure to 47 workplace substances. An increased myeloma risk (odds ratio [OR] = 1.2, 95 percent confidence interval [CI] = 1.0-1.5) was seen for women not in the Pension Fund, but who had an occupational title coded as 'Mrs/homemaker.' Nonsignificantly elevated risks of 1.3 or greater were observed for employment in: production of agricultural products; orchards/nurseries; spinning/weaving; other textile and plastics manufacturing; hotel, entertainment, and social services industries. Elevated, but nonsignificant risks were observed for possible and probable exposure to exhaust fumes, formaldehyde, wood dust, animals or animal products, and pesticides. The strongest association with myeloma was employment in the agricultural industry (OR = 1.5, CI = 0.8-2.8), however, the number of women who worked on family farms was unknown and could not be included in this risk estimate.

The objectives were to translate and culturally adapt the M.D. Anderson Dysphagia Inventory (MDADI) into Danish and subsequently test the reliability of the Danish version. The MDADI was translated into Danish and cross culturally adapted through cognitive interviews. The final version was test-retest evaluated in a group of head and neck cancer (HNC) patients who responded to the questionnaire twice with a mean of eight days apart. Interclass correlation coefficient, Cronbach's alpha, floor and ceiling effects, standard error of measurement and minimal detectable change were investigated. Fourteen patients were interviewed on the comprehensibility of the Danish MDADI, and all found the questionnaire meaningful, easy to understand, non-offensive and to include relevant aspects of dysphagia related to HNC. Sixty-four patients were included in the test-retest study. Especially, one item in the emotional scale (E7) appeared to be often misinterpreted, and ceiling effects were found in all four subdomains (global, emotional, functional and physical). The four subdomains and the composite score showed acceptable test-retest reliability and internal consistency in a Danish population of HNC patients. The Danish MDADI is reliable in terms of internal consistency and test-retest reproducibility and can be used in assessing the health-related quality of life in head and neck cancer patients with dysphagia.

Few risk factors for sporadic vestibular schwannoma (VS) are known. Several studies have proposed an increased risk with occupational noise exposure, whereas no studies have investigated residential traffic noise exposure as a risk factor. The present study investigated if residential traffic noise was associated with vestibular schwannoma in a large, population-based Danish case-control study. We identified 1454 VS cases, age above 30 years at diagnosis, between 1990 and 2007. For each case, we selected two random population controls, matched on sex and year of birth. Road and railway traffic noise at the residence was calculated for all present and historical addresses between 1987 and index date. Associations between traffic noise and risk for VS were estimated using conditional logistic regression, adjusted for education, disposable personal income, cohabitation status, railway noise exposure, municipal population density, and municipal income. A two-year time-weighted mean road traffic noise exposure was associated with an adjusted odds ratio of 0.92 (0.82-1.03) for developing VS, per 10 dB increment. There was no clear trend in categorical analyses. Similarly, linear and categorical analyses of residential railway noise did not suggest an association. We found no interaction with demographics, year of diagnosis, individual and municipal socioeconomic variables, and railway noise exposure. The results did not differ by tumor side, spread or size. The present study does not suggest an association between residential traffic noise and VS.

Objective General practitioners are the first point of contact in Danish out-of-hours (OOH) primary care. The large number of contacts implies that prescribing behaviour may have considerable impact on health-care expenditures and quality of care. The aim of this study was to examine the prevailing practices for medication prescription in Danish OOH with a particular focus on patient characteristics and contact type. Design and setting A one-year population-based retrospective observational study was performed of all contacts to OOH primary care in the Central Denmark Region using registry data. Main outcome measures Prescriptions were categorised according to Anatomical Therapeutic Chemical Classification (ATC) codes and stratified for patient age, gender and contact type (telephone consultation, clinic consultation or home visit). Prescription rates were calculated as number of prescriptions per 100 contacts. Results Of 644,777 contacts, 154,668 (24.0%) involved medication prescriptions; 21.9% of telephone consultations, 32.9% of clinic consultations and 14.3% of home visits. Around 53% of all drug prescriptions were made in telephone consultations. Anti-infective medications for systemic use accounted for 45.5% of all prescriptions and were the most frequently prescribed drug group for all contact types, although accounting for less than 1/3 of telephone prescriptions. Other frequently prescribed drugs were ophthalmological anti-infectives (10.5%), NSAIDs (6.4%), opioids (3.9%), adrenergic inhalants (3.0%) and antihistamines (2.3%). Conclusion About 25% of all OOH contacts involved one or more medication prescriptions. The highest prescription rate was found for clinic consultations, but more than half of all prescriptions were made by telephone.

This investigation presents results from a genetic characterization of 5 Danish dog breeds genotyped on the CanineHD BeadChip microarray with 170,000 SNP. The breeds investigated were 1) Danish Spitz (DS; n=8), 2) Danish-Swedish Farm Dog (DSF; n=18), 3) Broholmer (BR; n=22), 4) Old Danish Pointing Dog (ODP; n=24), and 5) Greenland Dog (GD; n=23). The aims of the investigation were to characterize the genetic profile of the abovementioned dog breeds by quantifying the genetic differentiation among them and the degree of genetic homogeneity within breeds. The genetic profile was determined by means of principal component analysis (PCA) and through a Bayesian clustering method. Both the PCA and the Bayesian clustering method revealed a clear genetic separation of the 5 breeds. The level of genetic variation within the breeds varied. The expected heterozygosity (HE) as well as the degree of polymorphism (P%) ranked the dog breeds in the order DS>DSF>BR>ODP>GD. Interestingly, the breed with a tenfold higher census population size compared to the other breeds, the Greenland Dog, had the lowest within-breed genetic variation, emphasizing that census size is a poor predictor of genetic variation. The observed differences in variation among and within dog breeds may be related to factors such as genetic drift, founder effects, genetic admixture, and population bottlenecks. We further examined whether the observed genetic patterns in the 5 dog breeds can be used to design breeding strategies for the preservation of the genetic pool of these dog breeds.

The article series provides a written and pictorial account of the Danish pharmaceutical industry's products from their introduction until about 1950. Part 3 deals with products from the company founded by Alfred Benzon in 1849. Alfred Nicolai Benzon owned the Swan Pharmacy in Copenhagen. In 1863 he started an independent company manufacturing branded pharmaceuticals, thus combining the pharmacy's activities with the wholesale business. The family owned the company until 1952, when it was converted into a foundation. After several restructuring rounds, the medicine production business continued as Benzon Pharma A/S until 1990, when Nycomed Pharma A/S bought up all the branded pharmaceuticals. As the first pharmaceutical company in Denmark, Alfred Benzon was an industrial frontrunner in the country at the time, supplying not only the domestic market but foreign markets as well. Alfred Benzon was the first Danish company to produce ether for anesthesia, and malt extract, a dietetic preparation. The high quality of both products made them valuable export articles. In the early 1890s, Alfred Benzon became the first Danish company to start the research-based production of extract of thyroid glands from slaughtered cattle. This was the beginning of a long-standing specialization in producing organotherapeutic substances from animal organs originating from Danish animal husbandry. In 1932 the company had 26 preparations of this type in its range, many of them on the market for several years. These medicine substances included iron preparations and effervescent salts followed by sulfonamides, synthetic hormones and a substance to counteract motion sickness.

Depression is associated with work absenteeism, reduced productivity, and significant personal and societal economic burden. We describe patterns and determinants of sick leave among working Danish antidepressant users. Persons starting antidepressant treatment (January 1, 2004 through December 31, 2005) were identified from a representative 25% sample of the Danish population by linking Danish national registries. Inclusion criteria were age 18-64 years, being in the workforce the week prior to the first antidepressant prescription (index prescription, IP), and no antidepressant prescription in the year prior to the IP. Only sick leaves >2 weeks are centrally registered in Denmark and could be assessed. Cox regression analyses identified predictors of sick leave during the year following the IP, based on previous history of sick leave and clinical and socio-demographic baseline characteristics. In the cohort of 25,908 (59.7% women), sick leave prevalence increased from 37.5% (year prior to IP) to 45.3% (year after the IP); 30.7% were on sick leave for >8 weeks. Incidence peaked (35.5% of individuals) the week after the IP. Of persons with sick leave in the year before the IP, 62.7% were on sick leave the first week after the IP, vs 5.7% of those without previous sick leave. Predictors associated with increased risk of sick leave among those without previous sick leave were unemployment, female gender, age 25-54 years, couples with children, and vocational and higher intermediate education (including e.g. teachers and nurses). Reasons for sick leave, sick leaves of less than 14 days and the indications for antidepressant treatment were unknown. Sick leave was prevalent in persons starting new antidepressant use, often lasting >8 weeks. Previous sick leave was the strongest predictor of subsequent sick leave. © 2013 Elsevier B.V.

An autosomal dominant mutation in the BRI2/ITM2B gene causes familial Danish dementia (FDD). Analysis of FDD(KI) mice, a mouse model of FDD genetically congruous to the human disease since they carry one mutant and one wild-type Bri2/Itm2b allele, has shown that the Danish mutation causes loss of Bri2 protein, synaptic plasticity and memory impairments. BRI2 is a physiological interactor of Aβ-precursor protein (APP), a gene associated with Alzheimer disease, which inhibits processing of APP. Here, we show that APP/Bri2 complexes are reduced in synaptic membranes of FDD(KI) mice. Consequently, APP metabolites derived from processing of APP by β-, α- and γ-secretases are increased in Danish dementia mice. APP haplodeficiency prevents memory and synaptic dysfunctions, consistent with a role for APP metabolites in the pathogenesis of memory and synaptic deficits. This genetic suppression provides compelling evidence that APP and BRI2 functionally interact, and that the neurological effects of the Danish form of BRI2 only occur when sufficient levels of APP are supplied by two alleles. This evidence establishes a pathogenic sameness between familial Danish and Alzheimer's dementias.

During recent decades, the prevalence of metabolic morbidity has increased rapidly in adult Greenlandic Inuit. To what extent this is also reflected in the juvenile Inuit population is unknown. The objective was, therefore, in the comparison with Danish children, to evaluate metabolic profiles in Greenlandic Inuit children from the capital in the southern and from the northern most villages 187 Inuit and 132 Danish children were examined with anthropometrics, pubertal staging, fasting blood samples, and a maximal aerobic test. Both Inuit children living in Nuuk and the northern villages had significantly higher glucose, total cholesterol, apolipoprotein A1 levels, and diastolic blood pressure compared with Danish children after adjustment for differences in adiposity and aerobic fitness levels. The Inuit children living in Nuuk had significantly higher BMI, body fat %, HbA1 c, and significantly lower aerobic fitness and ApoA1 levels than northern living Inuit children. Greenlandic Inuit children had adverse metabolic health profile compared to the Danish children, the differences where more pronounced in Inuit children living in Nuuk. The tendencies toward higher prevalence of diabetes and metabolic morbidity in the adult Greenlandic Inuit population may also be present in the Inuit children population.

We investigated the likelihood of ending a relationship among women who did not have a child after a fertility evaluation. Longitudinal cohort study. Danish women ever referred for primary or secondary fertility problems to a public Danish hospital or private fertility clinic between 1990 and 2006. A total of 47,515 women. The data were linked to Danish administrative population-based registries containing demographic and socioeconomic information. Discrete-time survival models were used with person-period data. Each woman was followed from the year of her initial fertility evaluation through to 2007. Effects of parity after a fertility evaluation on the likelihood of ending a marital or cohabitation relationship. After up to 12 years of follow up, nearly 27% of the women were no longer living with the person with whom they had lived at the time of the fertility evaluation. Women who did not have a child after the evaluation had significantly higher odds ratios for ending a relationship up to 12 years after the evaluation (with odds ratios up to 3.13, 95% CI 2.88-3.41) than women who had a child, regardless of their parity before the evaluation. Parity after a fertility evaluation may be an important component in the longitudinal relationships of couples with fertility problems. Studies with detailed information on marital quality and relational well-being of couples with fertility problems are needed. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

Danish youth has for years had the highest alcohol consumption in Europe, however recent surveys show that consumption levels have diminished slightly and that the age of first intoxication has been raised. To explore young moderate drinkers' attitudes, values, and behaviour in relation to alcohol consumption. Data consists of 10 individual semi-structured interviews with 16-17-year-old moderate drinkers attending high school in Copenhagen, Denmark. The study shows that the respondents perceive drinking as a necessity for feeling included at parties, but also that they do not feel a need to drink large amounts of alcohol in order to feel this social inclusion. The study finds that respondents employ a number of different behavioural and cognitive strategies aimed at controlling their own and close friends' drinking behaviour, and that short-term negative social implications are of much greater concern than long-term health consequences. In addition, the study shows that parents have a limited direct influence in this group. The study identifies a group of young people who have clearly defined restrictions as to what they consider positive drinking behaviour. As parents and long-term health consequences only have an limited influence on the respondents' drinking behaviour, these elements should not have primary focus in future interventions. In stead, interventions should take into account the social dynamics involved in drinking and recognise that the social qualities surrounding alcohol weighs higher among this group of young people than the quantity of alcohol consumed.

The aim of this paper is to present the conceptual framework for a Danish human biomonitoring (HBM) program. The EU and national science-policy interface, that is fundamental for a realization of the national and European environment and human health strategies, is discussed, including the need for a structured and integrated environmental and human health surveillance program at national level. In Denmark, the initiative to implement such activities has been taken. The proposed framework of the Danish monitoring program constitutes four scientific expert groups, i.e. i. Prioritization of the strategy for the monitoring program, ii. Collection of human samples, iii. Analysis and data management and iv. Dissemination of results produced within the program. This paper presents the overall framework for data requirements and information flow in the integrated environment and health surveillance program. The added value of an HBM program, and in this respect the objectives of national and European HBM programs supporting environmental health integrated policy-decisions and human health targeted policies, are discussed. In Denmark environmental monitoring has been prioritized by extensive surveillance systems of pollution in oceans, lakes and soil as well as ground and drinking water. Human biomonitoring has only taken place in research programs and few incidences of e.g. lead contamination. However an arctic program for HBM has been in force for decades and from the preparations of the EU-pilot project on HBM increasing political interest in a Danish program has developed.

The Danish oral health care service for children: an international appraisal.

Davies, G N; Downer, M C; Holloway, P J

1983-09-01

The Danish children's oral health care service has been so successful in achieving its objectives that it will need to change and adapt in order to survive. It is suggested that the service should gradually become community-based rather than child-based. This process can be commenced by introducing treatment for the elderly, the handicapped and the indigent, converting the school clinics to municipal oral health units. Although it is important that private practice is maintained, private dentists should be encouraged to work in the system part-time, leading teams of supporting auxiliary personnel trained within an integrated system. Eventually, the facilities could form the basis of primary health care centres. The lessons to be learnt from the Danish experience have a wider application to other countries. In developing countries it is obvious that they should first place limited dental resources into public health prevention and only invest in expensive treatment clinics as funds become more available. Manpower planning should ensure that personnel are not overtrained for the needs of the community. In developed countries, increasingly more resources will need to be channelled into adult dental care, and dental education must lead the profession into this new era. Difficult though these changes will be, the stable relationships that have developed between the various arms of the service under the guidance of the Danish Dental Association, will ensure that the profession will survive and flourish for the benefit of the Danish people.

Background: Perfluoroalkyl substances (PFASs) are persistent pollutants found to be endocrine disruptive and neurotoxic in animals. Positive correlations between PFASs and neurobehavioral problems in children were reported in cross-sectional data, but findings from prospective studies are limited. Objectives: We investigated whether prenatal exposure to PFASs is associated with attention deficit/hyperactivity disorder (ADHD) or childhood autism in children. Methods: Among 83,389 mother–child pairs enrolled in the Danish National Birth Cohort during 1996–2002, we identified 890 ADHD cases and 301 childhood autism cases from the Danish National Hospital Registry and the Danish Psychiatric Central Registry. From this cohort, we randomly selected 220 cases each of ADHD and autism, and we also randomly selected 550 controls frequency matched by child’s sex. Sixteen PFASs were measured in maternal plasma collected in early or mid-pregnancy. We calculated risk ratios (RRs) using generalized linear models, taking into account sampling weights. Results: Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) were detected in all samples; four other PFASs were quantified in ≥ 90% of the samples. We did not find consistent evidence of associations between mother’s PFAS plasma levels and ADHD [per natural log nanograms per milliliter increase: PFOS RR = 0.87 (95% CI: 0.74, 1.02); PFOA RR = 0.98 (95% CI: 0.82, 1.16)] or autism [per natural log nanograms per milliliter increase: PFOS RR = 0.92 (95% CI: 0.69, 1.22); PFOA RR = 0.98 (95% CI: 0.73, 1.31)]. We found positive as well as negative associations between higher PFAS quartiles and ADHD in models that simultaneously adjusted for all PFASs, but these estimates were imprecise. Conclusions: In this study we found no consistent evidence to suggest that prenatal PFAS exposure increases the risk of ADHD or childhood autism in children.

Well-being is considered a prerequisite for learning. The Danish Ministry of Education initiated the development of a new 40-item student well-being questionnaire in 2014 to monitor well-being among all Danish public school students on a yearly basis. The aim of this study was to investigate the basic psychometric properties of this questionnaire. We used the data from the 2015 Danish student well-being survey for 268,357 students in grades 4-9 (about 85% of the study population). Descriptive statistics, exploratory factor analyses, confirmatory factor analyses and Cronbach's α reliability measures were used in the analyses. The factor analyses did not unambiguously support one particular factor structure. However, based on the basic descriptive statistics, exploratory factor analyses, confirmatory factor analyses, the semantics of the individual items and Cronbach's α, we propose a four-factor structure including 27 of the 40 items originally proposed. The four scales measure school connectedness, learning self-efficacy, learning environment and classroom management. Two bullying items and two psychosomatic items should be considered separately, leaving 31 items in the questionnaire. The proposed four-factor structure addresses central aspects of well-being, which, if used constructively, may support public schools' work to increase levels of student well-being.

The aim of the Danish Anaesthesia Database (DAD) is the nationwide collection of data on all patients undergoing anesthesia. Collected data are used for quality assurance, quality development, and serve as a basis for research projects. The DAD was founded in 2004 as a part of Danish Clinical Registries (Regionernes Kliniske Kvalitetsudviklings Program [RKKP]). Patients undergoing general anesthesia, regional anesthesia with or without combined general anesthesia as well as patients under sedation are registered. Data are retrieved from public and private anesthesia clinics, single-centers as well as multihospital corporations across Denmark. In 2014 a total of 278,679 unique entries representing a national coverage of ~70% were recorded, data completeness is steadily increasing. Records are aggregated for determining 13 defined quality indicators and eleven defined complications all covering the anesthetic process from the preoperative assessment through anesthesia and surgery until the end of the postoperative recovery period. Registered variables include patients' individual social security number (assigned to all Danes) and both direct patient-related lifestyle factors enabling a quantification of patients' comorbidity as well as variables that are strictly related to the type, duration, and safety of the anesthesia. Data and specific data combinations can be extracted within each department in order to monitor patient treatment. In addition, an annual DAD report is a benchmark for departments nationwide. The DAD is covering the anesthetic process for the majority of patients undergoing anesthesia in Denmark. Data in the DAD are increasingly used for both quality and research projects.

Offspring of parents with exceptional longevity (OPEL), who are more likely to carry longevity-associated genotypes, may age more successfully than offspring of parents with usual survival (OPUS). Maintenance of physical function is a key attribute of successful aging. While many genetic and non-genetic factors interact to determine physical phenotype in aging, examination of the contribution of exceptional parental longevity to physical function in aging is limited. The LonGenity study recruited a relatively genetically homogenous cohort of Ashkenazi Jewish (AJ) adults age 65 and older, who were defined as either OPEL (having at least one parent who lived to age 95 or older) or OPUS (neither parent survived to age 95). Subjective and objective measures of physical function were compared between the two groups, accounting for potential confounders. Of the 893 LonGenity subjects, 365 were OPEL and 528 were OPUS. OPEL had better objective and subjective measures of physical function than OPUS, especially on unipedal stance (p = 0.009) and gait speed (p = 0.002). Results support the protective role of exceptional parental longevity in preventing decline in physical function, possibly via genetic mechanisms that should be further explored.

The purpose of the study was to study the circumstances and incidence rates of fatal accidents in inspection obligated and non-inspection obligated Danish fishing vessels to identify areas for prevention. Information about the fatalities came from maritime authority reports, including vessel disaster reports, post mortem reports, maritime inquiries and police reports. The person- and vessel years at risk came from the Danish Directorate of Fisheries. During the period 1989-2005, 114 fatalities occurred. Sixty-one of the fatalities occurred in 36 vessel disasters mainly caused by foundering/capsizing due to stability changes in rough weather and collisions; 39 fatal occupational accidents mainly occurred on the larger inspection obligated trawlers during fishing. In the remaining 14 other fatal accidents, the main causal factors were difficult embarking/disembarking conditions by darkness in foreign ports and alcohol intoxication. In the period 1995-2005, the overall incidence rate was 10 per 10,000 fishermen per year with no down-going trend during that period. The fatal accident rates are still too high, despite the efforts to reduce the risk. Increased focus on regular and repeated safety training for all fishermen and improved safety measures are needed, especially in the underscored areas of sea disasters concerning small vessels and occupational accidents on big vessels. Better registration of time at risk for fishermen is needed to validate the effect of the safety measures.

Antibodies to Coxiella burnetii have been found in the Danish dairy cattle population with high levels of herd and within herd seroprevalences. However, the prevalence of antibodies to C. burnetii in Danish beef cattle remains unknown. The objectives of this study were to (1) estimate the prevalence and (2) identify risk factors associated with C. burnetii seropositivity in Danish beef and dairy cattle based on sampling at slaughter. Eight hundred blood samples from slaughtered cattle were collected from six Danish slaughter houses from August to October 2012 following a random sampling procedure. Blood samples were tested by a commercially available C. burnetii antibody ELISA kit. A sample was defined positive if the sample-to-positive ratio was greater than or equal to 40. Animal and herd information were extracted from the Danish Cattle Database. Apparent (AP) and true prevalences (TPs) specific for breed, breed groups, gender and herd type; and breed-specific true prevalences with a random effect of breed was estimated in a Bayesian framework. A Bayesian logistic regression model was used to identify risk factors of C. burnetii seropositivity. Test sensitivity and specificity estimates from a previous study involving Danish dairy cattle were used to generate prior information. The prevalence was significantly higher in dairy breeds (AP=9.11%; TP=9.45%) than in beef breeds (AP=4.32%; TP=3.54%), in females (AP=9.10%; TP=9.40%) than in males (AP=3.62%; TP=2.61%) and in dairy herds (AP=15.10%; TP=16.67%) compared to beef herds (AP=4.54%; TP=3.66%). The Bayesian logistic regression model identified breed group along with age, and number of movements as contributors for C. burnetii seropositivity. The risk of seropositivity increased with age and increasing number of movements between herds. Results indicate that seroprevalence of C. burnetii is lower in cattle sent for slaughter than in Danish dairy cows in production units. A greater proportion of this prevalence

This study aims to describe the determinants related to gender differences in the GP utilization in Danish population aged 50-65 years. Cohort-based cross-sectional study. Danish general practice. Totally, 54,849 participants of the Danish Diet, Cancer and Health cohort (50-65 years). The sum of cohort members' face-to-face consultations with general practitioner (GP) at the cohort baseline year (1993-1997). We obtained data on GP visits from the Danish National Health Service Register at the cohort baseline (1993-1997), when information on lifestyle (smoking, body mass index (BMI), alcohol use, physical activity), medical conditions (somatic and mental), employment, education, gravidity, and hormone therapy (HT) use was collected by questionnaire. Women had on average 4.1 and men 2.8 consultations per year. In a crude model, women had 47% higher rate of GP visits than men (incidence rate ratio: 1.47; 95% Confidence Interval: 1.45-1.50), which remained unchanged after adjustment for lifestyle, socio-demographic and medical factors, but attenuated to 18% (1.18; 1.13-1.24) after adjustment for female factors (gravidity and post-menopausal HT. In a fully adjusted model, subjects with hypertension (1.63; 1.59-1.67), mental illness (1.63; 1.61-1.66), diabetes (1.56; 1.47-1.65), angina pectoris (1.28; 1.21-1.34), and unemployed persons (1.19; 1.18-1.21) had highest rates of GP visits. Gravidity and HT use explain a large proportion, but not all of the gender difference in GP utilization. Medical conditions (somatic and mental) and unemployment are the main determinants of GP utilization in men and women, while lifestyle has minor effect. Key points Female gender remained a dominant determinant of GP utilization, after adjustment for lifestyle, socio-demography, medical and gender specific factors, with females consulting their GP 18% more often than males. Female reproductive factors (use of postmenopausal hormone therapy and gravidity) explained a large proportion of

Genetic factors have been found to influence the risk of suicide. It is less clear if this also applies to attempted suicide. We have investigated genetic and familial environmental factors by studying the occurrence of suicide attempts in biological and adoptive siblings of adoptees who attempted suicide compared to siblings of adoptees with no suicide attempts. We used a random sample of 1933 adoptees from the Danish Adoption Register, a register of non-familial adoptions of Danish children, i.e. the adoptive parents are biologically unrelated to the adoptee. Analyses were conducted on incidence rates of attempted suicide in biological and adoptive siblings given occurrence of attempted suicide in the adoptees while also taking into account psychiatric disorders. Information about suicidal attempt and history of psychiatric disorder was based on hospital admissions. The rate of attempted suicide in full siblings of adoptees who attempted suicide before age 60 years was higher than in full siblings of adoptees who had not attempted suicide (incidence rate ratios (IRR)=3.45; 95% confidence interval [CI]=0.94-12.7). After adjustment for history of psychiatric admission of siblings the increased rate was statistically significant (IRR=3.88; 95% CI-1.42-10.6). Information on attempted suicide and psychiatric history was limited to that which involved hospitalisation. Genetic factors influence risk of suicide attempts. © 2013 Published by Elsevier B.V.

Limited evidence exists for an association between maternal diet during pregnancy and offspring bone health. In a prospective study, we examined the association between dietary patterns in mid-pregnancy and offspring forearm fractures. In total, 101,042 pregnancies were recruited to the Danish National Birth Cohort (DNBC) during 1996–2002. Maternal diet was collected by a food frequency questionnaire. Associations were analyzed between seven dietary patterns extracted by principal component analysis and offspring first occurrence of any forearm fracture diagnosis, extracted from the Danish National Patient Register, between time of birth and end of follow-up (<16 year) (n = 53,922). In multivariable Cox regression models, offspring of mothers in the fourth vs. first quintile of the Western pattern had a significant increased risk (Hazard ratio, 95% confidence interval: 1.11, 1.01–1.23) of fractures, and there was a borderline significant positive trend (p = 0.06). The other dietary patterns showed no associations and neither did supplementary analyses of macro- and micronutrients or single food groups, except for the intake of artificially sweetened soft drinks, which was positively associated with offspring forearm fractures (p = 0.02). In the large prospective DNBC high mid-pregnancy consumption of Western diet and artificially sweetened soft drinks, respectively, indicated positive associations with offspring forearm fractures, which provides interesting hypotheses for future research.

In 2011, the Danish Ministry of Food, Agriculture and Fisheries launched the Danish Organic Action Plan 2020 intending to double the organic agricultural area in Denmark. This study aims to measure experienced physical and psychological wellbeing at work along with beliefs and attitudes among kitchen workers before and after participating in educational training programmes in organic food conversion. This longitudinal study applied an online self-administered questionnaire among kitchen workers before and after the implementation of an organic food conversion programme with 1-year follow-up. The study targeted all staff members in the participating public kitchens taking part in the organic food conversion process funded by the Danish Organic Action Plan 2020. Of the 448 eligible kitchen workers, 235 completed the questionnaire at baseline (52%) and 149 at follow-up (63% of those surveyed at baseline). No substantive differences between baseline and follow-up measurements of organic food conversion were detected on physical or psychological wellbeing at work. Kitchen workers reported a significant improvement in the perceived food quality, motivation to work and application of nutritional guidelines. Reported organic food percentages for the kitchens also increased significantly (P< 0.001) and a shift from using ready-made food products to producing more food from base was indicated. Within 1 year, a significant increase in motivation to work among kitchen staff was observed with no substantive changes in physical or psychological wellbeing at work identified. The results support the Danish Organic Action Plan 2020 and initiatives of similar kind. © The Author 2015. Published by Oxford University Press on behalf of the European Public Health Association.

Chronic inflammation can lead to anaemia of chronic disease due to the sequestration of iron caused by inflammatory cytokines and the protein hepcidin. However, the effect of low-grade inflammation (LGI) on haemoglobin among healthy individuals is not known. This study examines the effect of LGI on haemoglobin among Danish blood donors. We performed multivariable linear regression to assess the effect of LGI (i.e. high-sensitivity C-reactive protein above 3 mg/l but below 10 mg/l) on haemoglobin in 17 322 Danish blood donors. We also performed multivariable logistic regression to evaluate the effect of LGI on the risk of having low haemoglobin (below the 10th percentile among men and women, respectively). We adjusted for donation activity, age, sex, low ferritin, oral contraceptives and menopause. All analyses were stratified by current smoking status. LGI was associated with lower haemoglobin (0·08 mm lower [0·12 g/dl], 95% confidence interval (CI): -0·11-0·05) and increased risk of low haemoglobin (OR = 1·22, 95% CI: 1·05-1·43) in non-smokers. Conversely, LGI was associated with higher haemoglobin in smokers (0·12 mm [0·19 g/dl], 95% CI: 0·06-0·18). In this first study of LGI and haemoglobin in healthy individuals, there was a negative association between LGI and haemoglobin in non-smokers. The association was positive in smokers, probably because smoking leads to both increased inflammation and increased haemoglobin through CO exposure. © 2016 International Society of Blood Transfusion.

The incidence of actinic keratosis (AK) is increasing, and several treatment options are available. The aim of this study was to describe clinical characteristics and treatment patterns in patients with AK treated by Danish dermatologists. A multicenter, non-interventional, cross-sectional study was conducted. Three dermatology hospital departments and seven private dermatology clinics enrolled eligible AK patients consecutively during one week. A total of 312 patients were included. Non-melanoma skin cancer (NMSC) was previously reported in 51.0% of patients and currently suspected in 9.4% of AK-affected anatomical regions. Lesions of AK were located primarily on the face (38.6%), scalp (12.8%), and hands (11.2%). Actinic keratosis commonly presented with multiple AK lesions (38.6%) and field cancerization (38.5%). The treatments used most frequently were cryotherapy (57.7%) and photodynamic therapy (PDT) with methyl aminolevulinate (17.1%) and imiquimod (11.2%). The likelihood of receiving cryotherapy was higher for men (odds ratio [OR] 1.65, 95% confidence interval [CI] 1.10-2.47) and increased with age (2.2% per year, 0.4-4.0%). PDT represented the most frequently applied treatment for severe actinic damage and was more likely to be prescribed to women (OR 4.08, 95% CI 2.22-7.47) and young patients (OR 0.97 per year, 95% CI 0.95-0.99). The prevalence of severe actinic damage (17.3% versus 9.6%) and intake of immunosuppressive medication (29.0 versus 2.0) were higher among hospital patients compared with those treated in private practices (P < 0.0001). The majority of AK patients in Danish dermatology clinics have a history of skin cancer, and NMSC is suspected in almost 10% of AK-affected regions. Cryotherapy is the most frequently used treatment overall, except in instances of severe actinic damage, in which PDT is the first-choice treatment. © 2015 The International Society of Dermatology.

No scientific consensus has been reached on whether active tobacco smoking causes breast cancer. We examine the association between active smoking and breast cancer risk in Denmark, which has some of the highest smoking and breast cancer rates in women worldwide. We used the data from a nationwide Danish Nurse Cohort on 21,867 female nurses (age > 44 years) who at recruitment in 1993 or 1999 reported information on smoking status, onset, duration, and intensity, as well as breast cancer risk factors. We obtained data on incidence of breast cancer from Danish Cancer Registry until 2013, and used Cox regression models to analyze the association between smoking and breast cancer. Of 21,831 women (mean age 53.2 years) 1162 developed breast cancer during 15.7 years of follow-up. 33.7% of nurses were current and 30.0% former smokers at cohort baseline. Compared to never smokers, we found increased risk of breast cancer of 18% in ever (hazard ratio and 95% confidence interval: 1.18; 1.04-1.34) and 27% in current (1.27; 1.11-1.46) smokers. We detected a dose-response relationship with smoking intensity with the highest breast cancer risk in women smoking >15 g/day (1.31; 1.11-1.56) or >20 pack-years (1.32; 1.12-1.55). Parous women who smoked heavily (>10 pack-years) before first childbirth had the highest risk of breast cancer (1.58; 1.20-2.10). Association between smoking and breast cancer was not modified by menopausal status, obesity, alcohol or hormone therapy use, and seemed to be limited to the estrogen receptor positive breast cancer subtype. Active smoking increases risk of breast cancer, with smoking before first birth being the most relevant exposure window.

Family functioning plays a pivotal role in the adaptation to illness of both individuals and families, especially among elderly patients. The Brief Family Assessment Measure Third Edition (Brief FAM-III) is among the most frequently used self-report instruments that measures family functioning. However, no Danish translation or measure of its psychometric properties in a Danish population is available. The purpose of this study was to translate the Brief FAM-III into Danish and then evaluate its psychometric properties in elderly patients. The Brief FAM-III was translated into Danish using the forward-backward translation procedure and examined its psychometric properties in 60 elderly patients (aged over 65) consecutively admitted to an acute medical ward. Internal consistency reliability was assessed by Cronbach's alpha coefficients, and confirmatory factor analysis was used to examine the construct validity of the Brief FAM-III. Evaluation of the Danish version of the Brief FAM-III confirmed the three-factor structure (General Scale, Self-Rating Scale and Dyadic Relationships Scale) identified in the original instrument. However, goodness-of-fit indicators showed a relatively poor model fit. Cronbach's alpha for the total scales of Brief FAM-III was 0.94 suggesting good internal consistency. The Danish version of the Brief FAM-III demonstrated satisfactory validity and reliability to assess family functioning among acutely admitted elderly Danish patients. We suggest that it may also be useful for monitoring family functioning over time or determining the effects of therapeutic interventions in elderly medical patients; however, further testing is recommended. © 2017 Nordic College of Caring Science.

To explore experiences with engaging community pharmacists in educational programmes on quality and safety in medication handling in residential facilities for the disabled. A secondary analysis of data from two Danish intervention studies where community pharmacists were engaged in educational programmes. Data included 10 semi-structured interviews with staff, five semi-structured interviews and three open-ended questionnaires with residential facility managers, and five open-ended questionnaires to community pharmacists. Data were thematically coded to identify key points pertaining to the themes 'pharmacists as educators' and 'perceived effects of engaging pharmacists in competence development'. As educators, pharmacists were successful as medicines experts. Some pharmacists experienced pedagogical challenges. Previous teaching experience and obtained knowledge of the local residential facility before teaching often provided sufficient pedagogical skills and tailored teaching to local needs. Effects of engaging community pharmacists included in most instances improved cooperation between residential facilities and community pharmacies through a trustful relationship and improved dialogue about the residents' medication. Other effects included a perception of improved patient safety, teaching skills and branding of the pharmacy. Community pharmacists provide a resource to engage in educational programmes on medication handling in residential facilities, which may facilitate improved cooperation between community pharmacies and residential facilities. However, development of pedagogical competences and understandings of local settings are prerequisites for facilities and pharmacists to experience the programmes as successful. © 2016 Royal Pharmaceutical Society.

A new pain questionnaire should be simple, be documented to have discriminative function, and be related to previously used questionnaires. Word meaning was validated by using bilingual Danish medical students and asking them to translate words taken from the Danish version of the McGill pain questionnaire into English. Evaluative word value was estimated using a visual analog scale (VAS). Discriminative function was assessed by having patients with one of six painful conditions (postherpetic neuralgia, phantom limb pain, rheumatoid arthritis, ankle fracture, appendicitis, or labor pain) complete the questionnaire. We were not able to find Danish words that were reliably back-translated to the English words 'splitting' or 'gnawing'. A simple three-word set of evaluative terms had good separation when rated on a VAS scale ('let' 17.5+/-6.5 mm; 'moderat' 42.7+/-8.6 mm; and 'staerk' 74.9+/-9.7 mm). The questionnaire was able to discriminate among the six painful conditions with 77% accuracy by just using the descriptive words. The accuracy of the questionnaire increased to 96% with the addition of evaluative terms (for pain at rest and with activity), chronicity (acute vs. chronic), and location of the pain. A Danish pain questionnaire that subjects and patients can self-administer has been developed and validated relative to the words used in the English McGill Pain questionnaire. The discriminative ability of the questionnaire among some common painful conditions has been tested and documented. The questionnaire may be of use in patient care and research.

Radon and leukemia in the Danish study: another source of dose.

Harley, Naomi H; Robbins, Edith S

2009-10-01

An epidemiologic study of childhood leukemia in Denmark (2,400 cases; 6,697 controls) from 1968 to 1994 suggested a weak, but statistically significant, association of residential radon exposure and acute childhood lymphoblastic leukemia (ALL). The Danish study estimated a relative risk (RR) = 1.56 (95% CI, 1.05-2.30) for a cumulative exposure of 1,000 Bq m-3 y. For an exposure duration of 10 y their RR corresponds to a radon concentration of 100 Bq m-3. There are two dose pathways of interest where alpha particles could damage potential stem cells for ALL. One is the alpha dose to bone marrow, and two is the dose to bronchial mucosa where an abundance of circulating lymphocytes is found. Compared with an exposure of about 1 mSv y-1 from natural external background, radon and decay products contribute an additional 10 to 60% to the bone marrow equivalent dose. The other pathway for exposure of T (or B) lymphocytes is within the tracheobronchial epithelium (BE). Inhaled radon decay products deposit on the relatively small area of airway surfaces and deliver a significant dose to the nearby basal or mucous cells implicated in human lung cancer. Lymphocytes are co-located with basal cells and are half as abundant. Using a 10-y exposure to 100 Bq m-3, our dose estimates suggest that the equivalent dose to these lymphocytes could approach 1 Sv. The relatively high dose estimate to lymphocytes circulating through the BE, potential precursor cells for ALL, provides a dose pathway for an association.

Organization and financing of the Danish health care system.

The present paper aims at giving a short overview of the organization and financing of the Danish health care system as of 1997-1998 when the SWOT panel evaluated the system. The overview follows the triangular model of a health care system. The Danish system is characterized by being decentralized and single-funded. The hospital sector is public, and hospitals are financed and run by the counties (with only a very small private hospital sector alongside). General practitioners are private entrepreneurs but work under contract for the counties. Hospitals are financed by global budgets, while general practitioners are paid by a mixed remuneration system of capitation fees and fee-for-service. During the past 20 years, the government has repeatedly imposed budget ceilings on the counties which has limited growth in the health care sector.

The Danish National Aquatic Monitoring and Assessment Programme (NOVA) was launched in 1988 following the adoption of the first Danish Action Plan on the Aquatic Environment in 1987 with the aim to reduce by 50% the nitrogen (N) loading and by 80% the phosphorus (P) loading to the aquatic environment. The 14 years of experience gathered from NOVA have shown that discharges of total N (TN) and P (TP) from point sources to the Danish Aquatic Environment have been reduced by 69% (N) and 82% (P) during the period 1989 2002. Consequently, the P concentration has decreased markedly in most Danish lakes and estuaries. Considerable changes in agricultural practice have resulted in a reduction of the net N-surplus from 136 to 88 kg N ha-1 yr-1 (41%) and the net P-surplus from 19 to 11 kg P ha-1 yr-1 (42%) during the period 1985 2002. Despite these efforts Danish agriculture is today the major source of both N (>80%) and P (>50%) in Danish streams, lakes and coastal waters. A non-parametric statistical trend analysis of TN concentrations in streams draining dominantly agricultural catchments has shown a significant (p<0.05) downward trend in 48 streams with the downward trend being stronger in loamy compared to sandy catchments, and more pronounced with increasing dominance of agricultural exploitation in the catchments. In contrast, a statistical trend analysis of TP concentrations in streams draining agricultural catchments did not reveal any significant trends. The large reduction in nutrient loading from point and non-point sources has in general improved the ecological conditions of Danish lakes in the form of increased summer Secchi depth, decreased chlorophyll a and reduced phytoplankton biomass. Major changes have also occurred in the fish communities in lakes, with positive cascading effects on water quality. In Danish estuaries and coastal waters only a few significant improvements in the ecological quality have been observed, although it is expected that the

The modified version of the patients' Perceived Involvement in Care Scale (M-PICS) is a tool designed to assess cancer patients' perceptions of patient-health care provider pain communication process. The objective of this study was to examine the psychometric properties of the shortened Danish version of the M-PICS (SDM-PICS). The validated English version of the M-PICS was translated into Danish following the repeated back-translation procedure. Cancer patients were recruited for the study from specialized pain management facilities. Thirty-three patients responded to the SDM-PICS, Danish Barriers Questionnaire II, Hospital Anxiety and Depression Scale, and Brief Pain Inventory Pain Severity Scale. A factor analysis of the SDM-PICS resulted in two factors: Factor one, patient information, consisted of four items assessing the extent to which the patient shared information with his/her health care provider, and Factor two, health care provider information, consisted of four items measuring the degree to which a health care provider was perceived as the one who shares information. Two separate items addressed the perceived level of information exchange between the patient and the health care provider. The SDM-PICS total had an internal consistency of 0.88. The SDM-PICS scores were positively related to pain relief and inversely related to the measures of cognitive pain management barriers, anxiety, and reported pain levels. The SDM-PICS seems to be a reliable and valid measure of perceived patient-health care provider communication in the context of cancer pain.

In selecting cows for higher milk yields and milk quality, it is important to understand how these traits are affected by the bovine genome. The major milk proteins exhibit genetic polymorphism and these genetic variants can serve as markers for milk composition, milk production traits, and technological properties of milk. The aim of this study was to investigate the relationships between casein (CN) genetic variants and detailed protein composition in Swedish and Danish dairy milk. Milk and DNA samples were collected from approximately 400 individual cows each of 3 Scandinavian dairy breeds: Swedish Red (SR), Danish Holstein (DH), and Danish Jersey (DJ). The protein profile with relative concentrations of α-lactalbumin, β-lactoglobulin, and α(S1)-, α(S2)-, κ-, and β-CN was determined for each milk sample using capillary zone electrophoresis. The genetic variants of the α(S1)- (CSN1S1), β- (CSN2), and κ-CN (CSN3) genes for each cow were determined using TaqMan SNP genotyping assays (Applied Biosystems, Foster City, CA). Univariate statistical models were used to evaluate the effects of composite genetic variants, α(S1)-β-κ-CN, on the protein profile. The 3 studied Scandinavian breeds differed from each other regarding CN genotypes, with DH and SR having similar genotype frequencies, whereas the genotype frequencies in DJ differed from the other 2 breeds. The similarities in genotype frequencies of SR and DH and differences compared with DJ were also seen in milk production traits, gross milk composition, and protein profile. Frequencies of the most common composite α(S1)-β-κ-CN genotype BB/A(2)A(2)/AA were 30% in DH and 15% in SR, and cows that had this genotype gave milk with lower relative concentrations of κ- and β-CN and higher relative concentrations of αS-CN, than the majority of the other composite genotypes in SR and DH. The effect of composite genotypes on relative concentrations of the milk proteins was not as pronounced in DJ. The

Specific dietary patterns, including the Mediterranean diet, have been associated with stroke prevention. Our aim was to investigate whether adherence to a healthy Nordic diet, including fish, apples and pears, cabbages, root vegetables, rye bread, and oatmeal, was associated with risk of stroke. Incident cases of stroke among 55 338 men and women from the Danish Diet, Cancer and Health cohort were identified from the Danish National Patient Register and verified by review of records. Cases of ischemic stroke were further subclassified based on etiology according to the TOAST classification system (Trial of Org 10172 in Acute Stroke Treatment). Information on diet was collected at baseline (1993-1997) using a semiquantitative food-frequency questionnaire. Cox proportional hazards models were used to estimate hazards ratios of total stroke and subtypes of ischemic and hemorrhagic stroke. During a median follow-up of 13.5 years, 2283 cases of incident stroke were verified, including 1879 ischemic strokes. Adherence to a healthy Nordic diet, as reflected by a higher Healthy Nordic Food Index score, was associated with a lower risk of stroke. The hazards ratio comparing an index score of 4 to 6 (high adherence) with an index score of 0 to 1 (low adherence) was 0.86 (95% confidence interval 0.76-0.98) for total stroke. Inverse associations were observed for ischemic stroke, including large-artery atherosclerosis. No trend was observed for hemorrhagic stroke; however, a statistically insignificant trend was observed for intracerebral hemorrhage. Our findings suggest that a healthy Nordic diet may be recommended for the prevention of stroke. © 2017 American Heart Association, Inc.

Since 1995, significant efforts by authorities and researchers have been directed towards addressing the nutritional problems in Danish hospitals and nursing homes. The purpose of this study was to investigate whether the increased focus on nutritional problems in patients and nursing home residents has resulted in measurable progress. A questionnaire-based study was carried out among foodservice managers in Danish hospitals (n=96) and nursing homes (n=898) in 1995 and 2002/3 (n=90) and (n=682), respectively. The study used compliance with selected issues in the official Danish recommendations for institutional food service as an indicator for progress. The issues included: using nutrient calculated recipes/menus, offering menu choice options, using feedback routines on acceptability of menus, maintaining nutritional steering committees, employing food and nutrition contact persons, employing official recommendations and offering choice between three different menu energy levels. Hospitals had a higher compliance compared to nursing homes. In 1995, this was the case for all questions asked and differences were statistically significant. Also in 2002/3, hospitals had a higher compliance, except in the case of established feedback routines. Differences were statistically significant. The results indicate that nutritional care is higher on the agenda in hospital, than in nursing homes. However, very little progress can be seen in compliance when results are analysed over the 8-year period. The only progress for nursing homes was that more homes had implemented feedback routines on acceptability of food service in 2002/3 than in 1995. The difference was statistically significant. For hospitals, however, no progress was found between 1995 and 2002/3. The attempts to improve the nutritional status of hospital patients and nursing home residents seem to have failed. Still, the initiatives taken to improve the situation seem relevant. Especially the nursing homes might

Cirrhosis, the prevalence of which is increasing, is a risk factor for osteoporosis and fractures. However, little is known of the actual risk of hip fractures in patients with alcoholic cirrhosis. Using linked primary and secondary care data from the English and Danish nationwide registries, we quantified the hip fracture risk in two national cohorts of patients with alcoholic cirrhosis. We followed 3,706 English and 17,779 Danish patients with a diagnosis of alcoholic cirrhosis, and we identified matched controls from the general populations. We estimated hazard ratios (HR) of hip fracture for patients vs. controls, adjusted for age, sex and comorbidity. The five-year hip fracture risk was raised both in England (2.9% vs. 0.8% for controls) and Denmark (4.6% vs. 0.9% for controls). With confounder adjustment, patients with cirrhosis had fivefold (adjusted HR 5.5; 95% CI 4.3-6.9), and 8.5-fold (adjusted HR 8.5; 95% CI 7.8-9.3) increased rates of hip fracture, in England and Denmark, respectively. This association between alcoholic cirrhosis and risk of hip fracture showed significant interaction with age (p <0.001), being stronger in younger age groups (under 45 years, HR 17.9 and 16.6 for English and Danish patients, respectively) than in patients over 75 years (HR 2.1 and 2.9, respectively). In patients with alcoholic cirrhosis, 30-day mortality following a hip fracture was 11.1% in England and 10.0% in Denmark, giving age-adjusted post-fracture mortality rate ratios of 2.8(95% CI 1.9-3.9) and 2.0(95% CI 1.5-2.7), respectively. Patients with alcoholic cirrhosis have a markedly increased risk of hip fracture and post-hip fracture mortality compared with the general population. These findings support the need for more effort towards fracture prevention in this population, to benefit individuals and reduce the societal burden. Alcoholic cirrhosis creates a large public health burden and is a risk factor for bone fractures. Based on data from England and

Danish Society of Insurance Medicine was formed in 1902 as an association between the Danish Society of Accident Insurance and the Danish Society of Life Insurance Medicine, both founded a year before. The purpose of the society is to apply and to further the scientific basis of insurance medicine. The meetings also play a role as a forum for discussions. The members of the society are all working part-time in an insurance company in Denmark (in contrast to many other countries where it is a full-time job). The members are mainly specialists in medicine and surgery. During the first half life of the society nearly all members were high-qualified doctors, i.e. professors and consultants at a university hospital in Copenhagen usually with a doctoral degree. These prominent doctors had a significant influence on insurance medicine in Denmark. The managing directors of the Insurance Companies were invited to the meetings. Many scientific works and textbooks were written on the subject. The society arranges two meetings yearly - one concerning with life insurance and one with accident-insurance medicine. Previously, the question put to the medical adviser was always "Which impairments can still be insured?", but today the question is the opposite "Which impairments are not insurable?" The members have increased to currently 112, still only men, but today the members are younger, comprise fewer professors and fewer with a doctoral degree. During the last 6 years, all interested members in the insurance companies have been invited to the meetings, providing a broader input for the discussions. The topic of the meeting is of current interest: new laws or a new treatment of a disease (medication, surgery) which has been introduced. One to three speakers open the meeting, followed by a discussion. The meetings are always concluded with a light meal and a glass of wine, in earlier days also with cigars and Danish schnaps. 190 meetings have been held during the last 100 years

Monitoring hospital outcomes and clinical processes as a measure of clinical performance is an integral part of modern health care. The risk-adjusted cumulative sum (CUSUM) chart is a frequently used sequential analysis technique that can be implemented to monitor a wide range of different types of outcomes. The aim of this study was to describe how risk-adjusted CUSUM charts based on population-based nationwide medical registers were used to monitor 30-day mortality in Danish hospitals and to give an example on how alarms of increased hospital mortality from the charts can guide further in-depth analyses. We used routinely collected administrative data from the Danish National Patient Registry and the Danish Civil Registration System to create risk-adjusted CUSUM charts. We monitored 30-day mortality after hospital admission with one of 77 selected diagnoses in 24 hospital units in Denmark in 2015. The charts were set to detect a 50% increase in 30-day mortality, and control limits were determined by simulations. Among 1,085,576 hospital admissions, 441,352 admissions had one of the 77 selected diagnoses as their primary diagnosis and were included in the risk-adjusted CUSUM charts. The charts yielded a total of eight alarms of increased mortality. The median of the hospitals' estimated average time to detect a 50% increase in 30-day mortality was 50 days (interquartile interval, 43;54). In the selected example of an alarm, descriptive analyses indicated performance problems with 30-day mortality following hip fracture surgery and diagnosis of chronic obstructive pulmonary disease. The presented implementation of risk-adjusted CUSUM charts can detect significant increases in 30-day mortality within 2 months, on average, in most Danish hospitals. Together with descriptive analyses, it was possible to use an alarm from a risk-adjusted CUSUM chart to identify potential performance problems.

No suitable Danish questionnaire exists to evaluate patient satisfaction with various patient reported outcome measures. Thus, the aim of this research project was to conduct a study on the translation and cultural adaption of an American patient reported experience measures questionnaire, "Patient Feedback Form", among Danish patients, and to examine selected psychometric properties within reliability. In the first phase of the study, the Patient Feedback Form was forward and backward translated following the methodology of existing guidelines. Subsequently, cognitive interviewing was performed with seven cancer patients and seven healthy persons (19-86 years old/6 men and 8 women) to ensure that questions were easy to understand and made sense to Danish interviewees. In the second phase, phone interviews were carried out with 95 prostate cancer patients after they had responded to the same Patient Feedback Form. Missing data was imputed using the Expectation-Maximization technique. To examine the structure of the questionnaire, an exploratory factor analysis was conducted. Cronbach's alpha was calculated to investigate internal consistency. There were only minor disagreements in the translation process, and the reconciliation went smoothly (phase 1). With regard to one item, however, it was difficult to reach a consensus. Through the qualitative validation process, the right solution was found. The results from the psychometric testing (phase 2) showed that four factors had an Eigen value > 1, but only one factor was extracted as the Scree plot had a clear "elbow", showing a one factor structure that explained 46.1% of the variance. The internal consistency was high as Cronbach's alpha was 0.89. The translated, culturally adapted, and validated version of the Patient Feedback Form seems to be suitable for measuring satisfaction with patient reported outcome measures in a Danish setting. While the results should be treated with caution due to the small sample

Bovine milk provides important minerals, essential for human nutrition and dairy product quality. For changing the mineral composition of the milk to improve dietary needs in human nutrition and technological properties of milk, a thorough understanding of the genetics underlying milk mineral contents is important. Therefore the aim of this study was to 1) estimate the genetic parameters for individual minerals in Danish Holstein (DH) (n=371) and Danish Jersey (DJ) (n=321) milk, and 2) detect genomic regions associated with mineral content in the milk using a genome-wide association study (GWAS) approach. For DH, high heritabilities were found for Ca (0.72), Zn (0.49), and P (0.46), while for DJ, high heritabilities were found for Ca (0.63), Zn (0.57), and Mg (0.57). Furthermore, intermediate heritabilities were found for Cu in DH, and for K, Na, P and Se in the DJ. The GWAS revealed a total of 649 significant SNP markers detected for Ca (24), Cu (90), Fe (111), Mn (3), Na (1), P (4), Se (12) and Zn (404) in DH, while for DJ, a total of 787 significant SNP markers were detected for Ca (44), Fe (43), K (498), Na (4), Mg (1), P (94) and Zn (3). Comparing the list of significant markers between DH and DJ revealed that the SNP ARS-BFGL-NGS-4939 was common in both breeds for Zn. This SNP marker is closely linked to the DGAT1 gene. Even though we found significant SNP markers on BTA14 in both DH and DJ for Ca, and Fe these significant SNPs did not overlap. The results show that Ca, Zn, P and Mg show high heritabilities. In combination with the GWAS results this opens up possibilities to select for specific minerals in bovine milk.

Other studies have shed light on specific types of seafarers' job stressors and job satisfaction. However, so far there have not been any systematic attempts to capture the motivational profile of seafarers when it comes to both work demands and work resources. The purpose of this study is to explore the motivational profiles of seafarers in the Danish merchant fleet by identifying factors which motivate or demotivate seafarers to stay in their specific profession. Furthermore, we examine if there is a difference in work motivators and demotivators between Danish seafaring officers and non-officers. Material and methods. A questionnaire was sent out to 560 Danish-speaking seafarers with a Danish postal address; 346 seafarers returned the questionnaire, equalling a 61% response rate. The work motivators which were identified were: duration of home leave, level of responsibility, and level of challenge. The main demotivating factors that were identified were: being away from home, shipping company´s HRM, and regulatory requirements. The results contribute to a deeper understanding of how seafarers perceive their occupation, and help to identify areas and aspects which might need change if employers want to retain their workforce in the long run. Overall, the results show that most of the job demands and job resources that seafarers perceive are psychosocial. When it comes to the best aspects of seafaring, over 70% of the answers were related to psychosocial factors rather than organizational or structural factors. In relation to the perceived worst aspects in seafaring, about 85% of the responses fell into psychosocial categories. The differences in the motivational profiles of officers and non-officers showed the importance of not only looking at the seafaring profession as a whole but also considering the different characteristics of various jobs onboard.

Researchers have described the documentation practices of perioperative nurses as flawed and characterized by subjectivity and poor quality, which is often related to both the documentation tool and the nurses' level of commitment. Studies suggest that documentation of nursing care in the OR places special demands on electronic health records (EHRs). The purpose of this study was to explore how the use of an EHR tailored to perioperative practice affects Danish perioperative nurses' documentation practices. This study was a follow-up to a baseline study from 2014. For three months in the winter of 2015 to 2016, six participants tested an EHR containing a Danish edition of a selected section of the Perioperative Nursing Data Set. This study relied on realistic evaluation and participant observations to generate data. We found that nursing leadership was essential for improving perioperative nurses' documentation practices and that a tailored EHR may improve documentation practices. Copyright © 2017 AORN, Inc.

2006-10-01

The present study aimed to investigate whether organic conversion in catering has positive effects on the nutritional quality of menus offered. The methodology was based on a self-administered questionnaire. The self-declared priority given to the use of organic foods was measured as the basis for assigning catering managers to one of two groups: 'green' or 'non-green' caterers. These groups were then compared with regard to the relative nutritional quality of the menu options offered to customers. The study was carried out among randomly selected Danish worksite catering outlets. The subjects participating in the study comprised 526 Danish worksite catering managers. The results showed a strong correlation between caterers' 'green-ness' and the nutritional quality of the menu options offered. Green caters had more healthy options in their menus than non-green caters, which is likely to result in improved nutritional quality of the diets of end consumers. The reason for this may partly be the increased service training efforts that green caterers practise in order to be able to implement organic foods successfully. It may also be associated with the fact that the price premiums and availability of the organic products forces caterers to serve menus with higher amounts of root and non-green leafy vegetables, pulses and seasonal vegetables. The present findings suggest that organic conversion of public canteens may be a good opportunity to promote healthier eating in public catering.

Optimal treatment strategy for the oldest patients with diffuse large B-cell lymphoma (DLBCL) remains controversial, as this group often is precluded from clinical trials, and population-based studies are limited. All Danish DLBCL-patients ≥75 years diagnosed from 2003 to 2012 were identified, using the Danish National Lymphoma Registry (LYFO). Information regarding baseline characteristics, treatment, comorbidities and outcomes was retrieved from LYFO, the Danish National health registries and medical records. Patients were stratified by age (75-79; 80-84 and 85 + years), comorbidity score and treatment modality (standard treatment [R-CHOP/CHOP-like], less intensive regimens or palliative treatment). A total of 1011 patients were included. Standard treatment was initiated in 64%, ranging from 83% among patients aged 75-79 years to 32% among patient aged 85 + years. With standard treatment, median overall survival (OS) estimates were 4·6, 2·6, and 1·9 years for the age groups 75-79, 80-84 and 85+ years. Among patient aged 75-79 and 80-84 years, OS was superior with standard treatment, although high comorbidity scores attenuated this association. Among patients aged 85+ years, survival was not influenced by treatment intensity. Patients ≥80 years had similar OS regardless of intended (R-)CHOP dosing, whereas patients of 75-79 years scheduled for full dose had higher OS. Standard treatment was not associated with increased hospitalisation. Standard treatment is feasible with good outcomes in a large proportion of elderly DLBCL-patients. Planned dose reduction in patients aged ≥80 years had no negative impact on OS. Copyright © 2018 Elsevier Ltd. All rights reserved.

A healthy and productive working life has attracted attention owing to future employment and demographic challenges. The aim was to translate and adapt the Work Role Functioning Questionnaire (WRFQ) 2.0 to Norwegian and Danish. The WRFQ is a self-administered tool developed to identify health-related work limitations. Standardised cross-cultural adaptation procedures were followed in both countries' translation processes. Direct translation, synthesis, back translation and consolidation were carried out successfully. A pre-test among 78 employees who had returned to work after sickness absence found idiomatic issues requiring reformulation in the instructions, four items in the Norwegian version, and three items in the Danish version, respectively. In the final versions, seven items were adjusted in each country. Psychometric properties were analysed for the Norwegian sample (n = 40) and preliminary Cronbach's alpha coefficients were satisfactory. A final consensus process was performed to achieve similar titles and introductions. The WRFQ 2.0 cross-cultural adaptation to Norwegian and Danish was performed and consensus was obtained. Future validation studies will examine validity, reliability, responsiveness and differential item response. The WRFQ can be used to elucidate both individual and work environmental factors leading to a more holistic approach in work rehabilitation.

Previous studies have suggested an increased risk of amyotrophic lateral sclerosis (ALS) and other motor neuron diseases for those in occupations commonly exposed to diesel exhaust (DE). In this study, we investigated the association between occupational exposures to DE and odds of ALS. ALS cases were identified from the Danish National Patient Registry 1982 to 2013 and individually matched to 100 controls per case based on birth year and sex. Using occupational history since 1964 from the Danish Pension Fund, Cumulative DE exposures were estimated using a job exposure matrix. Associations were evaluated using conditional logistic regression analyses and stratified by sex. DE exposure at 10-year lag periods was positively associated with ALS in men ever exposed (aOR: 1.20; 95% CI: 1.05, 1.38). For men with > 50% probability of DE exposure, we observed a positive association with ALS and the highest quartile exposures during the 5-year lag period (aOR: 1.40; 95% CI: 1.11, 1.78) and 10-year lag period (aOR: 1.41; 95% CI: 1.11, 1.79). Our study suggests an association between consistently higher exposures to DE and ALS in men but not in women. These findings support those of previously reported associations between ALS and commonly DE exposed occupations.

Hospitalisation with otitis media in early childhood and cognitive function in young adult life: a prevalence study among Danish conscripts

PubMed Central

2013-01-01

Background Otitis media (OM) is a very common condition in children and occurs during years that are critical to the development of learning, literacy, and math skills. Therefore, among a large cohort of Danish conscripts, we aimed to examine the association between hospitalisation with OM in early childhood and cognitive function and educational level in early adulthood. Methods We conducted a population-based prevalence study using linked data from healthcare databases and conscription records of Danish men born between 1977 and 1983. We identified all hospitalisations with OM before 8 years of age. Cognitive function was measured by the Boerge Prien validated group intelligence test (Danish Børge Prien Prøve, BPP). We adjusted for potential confounders with and without stratification by hearing impairment. Furthermore, we examined the association between hospitalisation with OM and the prevalence of having achieved a General Certificate of Secondary Education (GCSE), stratified by quartiles of BPP scores. Results Of the 18 412 eligible conscripts aged 18–25 years, 1000 (5.5%) had been hospitalised with OM before age 8. Compared with conscripts without such a record, the adjusted prevalence ratio (PR) for a BPP score in the bottom quartile was 1.20 (95% confidence interval [CI]: 1.09–1.33). There was no major difference in the proportion of men with a GCSE and those without among those hospitalised with OM in early childhood. For men in the bottom and upper quartiles of BPP scores, the PRs for early childhood hospitalisation with OM were 0.89 (95% CI: 0.59–1.33) and 0.96 (95% CI, 0.88–1.05), respectively. Among men with severe hearing impairment, the proportion with a BPP score in the bottom quartile did not differ between those with and without an OM hospitalisation [PR = 1.01 (95% CI: 0.78–1.34)]. Conclusions Overall, we found that hospitalisation with OM in early childhood was associated with a slightly lower cognitive function in early

Specialised palliative care (SPC) takes place in specialised services for patients with complex symptoms and problems. Little is known about what determines the admission of patients to SPC and whether there are differences in relation to institution type. The aims of the study were to investigate whether cancer patients' admittance to SPC in Denmark varied in relation to sex, age and diagnosis, and whether the patterns differed by type of institution (hospital-based palliative care team/unit, hospice, or both). This was a register-based study of adult patients living in Denmark who died from cancer in 2010-2012. Data sources were the Danish Palliative Care Database, Danish Register of Causes of Death and Danish Cancer Registry. The associations between the explanatory variables (sex, age, diagnosis) and admittance to SPC were investigated using logistic regression. In the study population (N = 44,548) the overall admittance proportion to SPC was 37%. Higher odds of overall admittance to SPC were found for women (OR = 1.23; 1.17-1.28), younger patients (<40 compared with 80+ years old) (OR = 6.44; 5.19-7.99) and patients with sarcoma, pancreatic and stomach cancers, whereas the lowest were for patients with haematological malignancies. The higher admission found for women was most pronounced for hospices compared to hospital-based palliative care teams/units, whereas higher admission of younger patients was more pronounced for hospital-based palliative care teams/units. Patients with brain cancer were more often admitted to hospices, whereas patients with prostate cancer were more often admitted to hospital-based palliative care teams/units. It is unlikely that the variations in relation to sex, age and cancer diagnoses can be fully explained by differences in need. Future research should investigate whether the groups having the lowest admittance to SPC receive sufficient palliative care elsewhere.

Greenhouse gas (GHG) emissions from agriculture are a significant contributor to total Danish emissions. Consequently, much effort is currently given to the exploration of potential strategies to reduce agricultural emissions. This paper presents results from a study estimating agricultural GHG emissions in the form of methane, nitrous oxide and carbon dioxide (including carbon sources and sinks, and the impact of energy consumption/bioenergy production) from Danish agriculture in the years 1990-2010. An analysis of possible measures to reduce the GHG emissions indicated that a 50-70% reduction of agricultural emissions by 2050 relative to 1990 is achievable, including mitigation measures in relation to the handling of manure and fertilisers, optimization of animal feeding, cropping practices, and land use changes with more organic farming, afforestation and energy crops. In addition, the bioenergy production may be increased significantly without reducing the food production, whereby Danish agriculture could achieve a positive energy balance.

Up to 85% of patients with schizophrenia demonstrate cognitive dysfunction in at least one domain. Cognitive dysfunction plays a major role in functional outcome. It is hypothesized that addition of cognitive training to a comprehensive psychosocial programme (OPUS) enhances both cognitive and everyday functional capacity of patients more than the comprehensive psychosocial programme alone. The NEUROCOM trial examines the effect on cognitive functioning and everyday functional capacity of patients with schizophrenia of a 16-week manualised programme of individual cognitive training integrated in a comprehensive psychosocial programme versus the comprehensive psychosocial programme alone. The cognitive training consists of four modules focusing on attention, executive functioning, learning, and memory. Cognitive training involves computer-assisted training tasks as well as practical everyday tasks and calendar training. It takes place twice a week, and every other week the patient and trainer engage in a dialogue on the patient's cognitive difficulties, motivational goals, and progress in competence level. Cognitive training relies on errorless learning principles, scaffolding, and verbalisation in its effort to improve cognitive abilities and teach patients how to apply compensation strategies as well as structured problem solving techniques. At 16-week post-training and at ten-months follow-up, assessments are conducted to investigate immediate outcome and possible long-term effects of cognitive training. We conduct blinded assessments of cognition, everyday functional capacity and associations with the labour market, symptom severity, and self-esteem. Results from four-month and ten-month follow-ups have the potential of reliably providing documentation of the long-term effect of CT for patients with schizophrenia. Clinicaltrials.gov NCT00472862.

The aim of this study was to examine depression as a potential negative health effect of long work hours, anticipating an exposure-response relationship. A nationwide prospective cohort study of 2790 Danish senior medical consultants was conducted (61.7% response rate). With the consent of Danish Data Protection Agency, data from a questionnaire survey was linked with data from a Medical Products Agency Register. Long work hours were defined based on a self-reported average of weekly work hours >40, while redemption of anti-depressive (AD) drug prescriptions defined depression. Proportional hazards Cox regression analyses were conducted adjusting for gender, age, marital status, medical specialty, decision authority at work, work social support, quantitative work demands, and AD drugs prescribed before baseline. Long weekly work hours did not increase the risk of redeeming AD drug prescriptions at all times during follow-up compared to the reference of 37-40 work hours [41-44 hours: hazard ratio (HR) 0.95, 95% confidence interval (95% CI) 0.5-1.8; 45-49 hours: HR 0.88, 95% CI 0.4-1.8; 50-54 hours: HR 0.83, 95% CI 0.3-2.1; 55-59 hours: HR 0.67, 95% CI 0.2-2.9; ≥ 60 hours: HR 0.48, 95% CI 0.1-3.7]. The same result emerged when work hours was applied in a continuous form (from 25-36 hours to 37-40 hours to 41-44 hours and so on) (HR 0.93, 95% CI 0.76-1.13) and when robust analyses were conducted (data not shown). This study does not support the anticipation that long work hours increase the risk of depression. If anything, long work hours vaguely appear to decrease the risk of redeeming AD drug prescriptions.

To analyze the distribution of depressive, anxiety, and somatization symptoms across different occupational positions in a random sample of Danish residents. The study sample consisted of 591 Danish residents (50% women), aged 20-65, drawn from an age- and gender-stratified random sample of the Danish population. Participants filled out a survey that included the 92 item version of the Hopkins Symptom Checklist (SCL-92). We categorized occupational position into seven groups: high- and low-grade non-manual workers, skilled and unskilled manual workers, high- and low-grade self-employed, and unemployed. Compared to the reference group of high-grade non-manual workers, the depressive symptom score was statistically significantly elevated among unskilled manual workers (P = 0.043) and the unemployed (P < 0.001), after adjustment for age, gender, cohabitation, life events, and low household income. The anxiety symptom score was elevated only among the unemployed (P = 0.004). The somatization symptom score was elevated among unskilled manual workers (P = 0.002), the low-grade self-employed (P = 0.023), and the unemployed (P = 0.001). When we analyzed caseness of severe symptoms, we found that unskilled manual workers (OR = 3.27, 95% CI = 1.06-10.04) and the unemployed (OR = 6.20, 95% CI = 1.98-19.42) had a higher prevalence of severe depressive symptoms, compared to the reference group of high-grade non-manual workers. The unemployed also had a higher prevalence of severe somatization symptoms (OR = 6.28, 95% CI = 1.39-28.46). Unskilled manual workers, the unemployed, and, to a lesser extent, the low-grade self-employed showed an increased level of mental distress. Activities to promote mental health in the Danish population should be directed toward these groups.

Perfluoroalkyl substances (PFASs) are persistent pollutants found to be endocrine disruptive and neurotoxic in animals. Positive correlations between PFASs and neurobehavioral problems in children were reported in cross-sectional data, but findings from prospective studies are limited. We investigated whether prenatal exposure to PFASs is associated with attention deficit/hyperactivity disorder (ADHD) or childhood autism in children. Among 83,389 mother-child pairs enrolled in the Danish National Birth Cohort during 1996-2002, we identified 890 ADHD cases and 301 childhood autism cases from the Danish National Hospital Registry and the Danish Psychiatric Central Registry. From this cohort, we randomly selected 220 cases each of ADHD and autism, and we also randomly selected 550 controls frequency matched by child's sex. Sixteen PFASs were measured in maternal plasma collected in early or mid-pregnancy. We calculated risk ratios (RRs) using generalized linear models, taking into account sampling weights. Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) were detected in all samples; four other PFASs were quantified in ≥ 90% of the samples. We did not find consistent evidence of associations between mother's PFAS plasma levels and ADHD [per natural log nanograms per milliliter increase: PFOS RR = 0.87 (95% CI: 0.74, 1.02); PFOA RR = 0.98 (95% CI: 0.82, 1.16)] or autism [per natural log nanograms per milliliter increase: PFOS RR = 0.92 (95% CI: 0.69, 1.22); PFOA RR = 0.98 (95% CI: 0.73, 1.31)]. We found positive as well as negative associations between higher PFAS quartiles and ADHD in models that simultaneously adjusted for all PFASs, but these estimates were imprecise. In this study we found no consistent evidence to suggest that prenatal PFAS exposure increases the risk of ADHD or childhood autism in children.

Vowel bias in Danish word-learning: processing biases are language-specific.

Højen, Anders; Nazzi, Thierry

2016-01-01

The present study explored whether the phonological bias favoring consonants found in French-learning infants and children when learning new words (Havy & Nazzi, 2009; Nazzi, 2005) is language-general, as proposed by Nespor, Peña and Mehler (2003), or varies across languages, perhaps as a function of the phonological or lexical properties of the language in acquisition. To do so, we used the interactive word-learning task set up by Havy and Nazzi (2009), teaching Danish-learning 20-month-olds pairs of phonetically similar words that contrasted either on one of their consonants or one of their vowels, by either one or two phonological features. Danish was chosen because it has more vowels than consonants, and is characterized by extensive consonant lenition. Both phenomena could disfavor a consonant bias. Evidence of word-learning was found only for vocalic information, irrespective of whether one or two phonological features were changed. The implication of these findings is that the phonological biases found in early lexical processing are not language-general but develop during language acquisition, depending on the phonological or lexical properties of the native language. © 2015 John Wiley & Sons Ltd.

No Correlation Between Work-Hours and Operative Volumes--A Comparison Between United States and Danish Operative Volumes Achieved During Surgical Residency.

Since 2003, United States residents have been limited to an 80-hour workweek. This has prompted concerns of reduced educational quality, especially inadequate operating exposure. In contrast, the Danish surgical specialty-training program mandates a cap on working hours of 37 per week. We hypothesize that there is no direct correlation between work-hours and operative volume achieved during surgical residency. To test the hypothesis, we compare Danish and US operative volumes achieved during surgical residency training. Retrospective comparative study. The data from the US population was extracted from the Accreditation Council for Graduate Medical Education database for General Surgery residents from 2012 to 2013. For Danish residents, a questionnaire with case categories matching the Accreditation Council for Graduate Medical Education categories were sent to all Danish surgeons graduating the national surgical residency program in 2012 or 2013, 54 in total. In all, 30 graduated residents (55%) responded to the Danish survey. We found no significant differences in mean total major procedures (1002.4 vs 976.9, p = 0.28) performed during residency training, but comparing average major procedures per year, the US residents achieve significantly more (132.3 vs 195.4, p <0.01). When factoring in differences in time spent in training, this amounts to a weekly average difference of 1.2 cases throughout training. In this study, we find no difference in overall surgical volumes between Danes and US residents during their surgical training. When time in training was accounted for, differences between weekly surgical volumes achieved were minor, indicating a lack of direct correlation between weekly work-hours and operative volumes achievable. Factors other than work-hours seem to effect on operative volumes achieved during training. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

This study assessed the management of the organic household waste in the Danish-German border region and points out major differences between the systems and their potential effects on the environment using life cycle assessment (LCA). The treatment of organic waste from households in the Danish-German border region is very different on each side of the border; the Danish region only uses incineration for the treatment of organic household waste while the German region includes combined biogas production and composting, mechanical and biological treatment (MBT) and incineration. Data on all parts of the organic waste treatment was collected including waste composition data and data from treatment facilities and their respective energy systems. Based on that the organic waste management systems in the border region were modelled using the EASETECH waste management LCA-model. The main output is a life cycle assessment showing large differences in the environmental performance of the two different regions with the Danish region performing better in 10 out of 14 impact categories. Furthermore, the importance of the substituted district heating systems was investigated showing an impact up to 34% of the entire system for one impact category and showing large difference between each heating system substituted, e.g. in "Global Warming" the impact was from -16 to -1.1 milli person equivalent/tonne treated waste from substitution of centralised hard coal and decentralised natural gas, respectively.

Catheter ablation for atrial fibrillation (AF) is an important but expensive procedure that is the subject of some debate. Physicians' attitudes toward catheter ablation may influence promotion and patient acceptance. This is the first study to examine the attitudes of Danish cardiologists toward catheter ablation for AF, using a nationwide survey. We developed a purpose-designed questionnaire to evaluate attitudes toward catheter ablation for AF that was sent to all Danish cardiologists (n = 401; response n = 272 (67.8%)). There was no association between attitudes toward ablation and the experience or age of the cardiologist with respect to patients with recurrent AF episodes with a duration of <48 hours or >7 days and/or need for cardioversion. The majority (69%) expected a recurrence of AF after catheter ablation in more than 30% of the cases. For patients with persistent longstanding AF with a duration of >1 year, the attitude toward ablation for longstanding AF was more likely to be positive with increasing age (P < 0.01) and years of experience of the cardiologist (P = 0.002). Danish cardiologists generally have a positive attitude toward catheter ablation for AF, maintain up-to-date knowledge of the procedure, and are aware what information on ablation treatment should be given to patients with AF. The cardiologists had a positive attitude toward ablation for AF in patients with AF episodes <48 hours and patients with episodes >7 days, or those who needed medical/electrical conversion, but a more negative attitude toward treating longstanding AF patients. © 2015 Wiley Periodicals, Inc.

Little is known about whether the socio-economic status of parents is linked to their children becoming overweight. This study examined the association between parents' educational level and overweight Danish children in a nationally representative sample. Body mass index was calculated for a random sample of 512 children aged from four to 14 from the Danish National Survey of Diet and Physical Activity 2005-2008. Their parents provided weight and height data during an interview, together with details of their own educational level. Children were classified as overweight/obese in accordance with the International Obesity Task Force. Frequency estimates of prevalence and logistic regression models were used to correlate childhood overweight/obesity with the mothers' and fathers' educational levels as the main outcome measures. Danish mothers tended to be more highly educated than fathers and their educational level was inversely associated with their child being overweight, especially if it was a boy. However, the highest educational level of the parents was the only significant educational variable, suggesting that education was associated with overweight children irrespective of the gender of the parent. Public health initiatives should target parents with low educational levels to prevent, and reduce, social inequality in overweight children. ©2014 Foundation Acta Paediatrica.

Patient-reported outcome (PRO) instruments are increasingly being included in research and clinical practice to assess the patient point of view. Bariatric and body contouring surgery has the potential to improve or restore a patient's body image and health-related quality of life (HR-QOL). A new PRO instrument, called the BODY-Q, has recently been developed specifically for this patient group. The aim of the current study was to translate and perform a linguistic validation of the BODY-Q for use in Danish bariatric and body contouring patients. The translation was performed in accordance with the International Society For Pharmacoeconomics and Outcomes Research (ISPOR) and the World Health Organization (WHO) recommendations. Main steps taken included forward and backward translations, an expert panel meeting, and cognitive patient interviews. All translators aimed to conduct a conceptual translation rather than a literal translation and used a simple and clear formulation to create a translation understandable for all patients. The linguistic translation process led to a conceptually equivalent Danish version of the BODY-Q. The comparison between the back translation of the first Danish version and the original English version of the BODY-Q identified 18 items or instructions requiring re-translation. The expert panel helped to identify and resolve inadequate expressions and concepts of the translation. The panel identified 31 items or instructions that needed to be changed, while the cognitive interviews led to seven major revisions. The impact of weight loss methods such as bariatric surgery and body contouring surgery on patients' HR-QOL would benefit from input from the patient perspective. A thorough translation and linguistic validation must be considered an essential step when implementing a PRO instrument to another language and/or culture. A combination of the ISPOR and WHO guidelines contributed to a straightforward and thorough translation methodology

In the years following military deployment, soldiers may experience problems integrating into the community. However, little is known about the nature and prevalence of these problems and if they relate to posttraumatic symptomatology. In a prospective, longitudinal study of Danish soldiers deployed to Afghanistan in 2009 (N = 743), we assessed community reintegration difficulties 2.5 years after home coming (study sample: N = 454). Furthermore, symptoms of posttraumatic stress disorder (PTSD) were assessed before, during, and after deployment. Trajectories of PTSD symptoms from a previously published latent growth mixture modeling analysis were used to address whether community reintegration difficulties differ as a result of course and level of PTSD symptoms. Between 3.6 and 18.0% reported to have some, a lot, or extreme difficulties in reintegration domains such as interpersonal functioning, productivity, community involvement, and self-care. Mean level of reintegration difficulties differed significantly across six PTSD symptom trajectories (range 6.35-36.00); with more symptomatic trajectories experiencing greater community reintegration difficulties. Reintegration difficulties after deployment are present in less than 20% of Danish soldiers who return from Afghanistan. Difficulties are greater in individuals who follow symptomatic PTSD trajectories in the first years following deployment than in those who follow a low-stable trajectory with no or few symptoms.

Research suggests that addressing dying patients' existential concerns can improve their quality of life. We aimed to illuminate dying patients' existential concerns about the impending death through a descriptive analysis of semistructured interviews with 17 patients in Danish hospices. The main findings demonstrated how the patients faced the imminent death without being anxious of death but sorrowful about leaving life. Some patients expressed that they avoided thinking about death. They wished to focus on positive aspects in their daily life. We argue that the patients' existential concerns could not be fully captured by Yalom's existential psychology or by Kübler-Ross's theory about death stages. Patients' complex concerns could be more fully explained taking an outset in Heidegger's phenomenological thinking. © The Author(s) 2014.

The aims of this study were (i) to describe the trends in the work environment in 1990-2000 among employees in Denmark and (ii) to establish whether these trends were attributable to labor-force changes. The split-panel design of the Danish Work Environment Cohort Study includes interviews with three cross-sections of 6067, 5454, and 5404 employees aged 18-59 years, each representative of the total Danish labor force in 1990, 1995 and 2000. In the cross-sections, the participation rate decreased over the period (90% in 1990, 80% in 1995, 76% in 2000). The relative differences in participation due to gender, age, and region did not change noticeably. Jobs with decreasing prevalence were clerks, cleaners, textile workers, and military personnel. Jobs with increasing prevalence were academics, computer professionals, and managers. Intense computer use, long workhours, and noise exposure increased. Job insecurity, part-time work, kneeling work posture, low job control, and skin contact with cleaning agents decreased. Labor-force changes fully explained the decline in low job control and skin contact to cleaning agents and half of the increase in long workhours, but not the other work environment changes. The work environment of Danish employees improved from 1990 to 2000, except for increases in long workhours and noise exposure. From a specific work environment intervention point of view, the development has been less encouraging because declines in low job control, as well as skin contact to cleaning agents, were explained by labor-force changes.

The aim of this study was to investigate if the outcome of excessively crying infants treated with chiropractic manipulation (1) was associated with age and/or (2), at least partially, can be explained by age according to the natural decline in crying. This was a retrospective evaluation of clinical records of 749 infants from a private Danish chiropractic practice. All of the infants were healthy, thriving infants born to term within the age of 0 to 3 months who fulfilled the diagnostic criteria for excessively crying infants (infantile colic), whose parents sought chiropractic treatment. The infants were treated using chiropractic management as decided by the treating doctor of chiropractic, and changes in crying based upon the parents' report were noted as improved, uncertain, or nonrecovered. Age predictor groups were cross-tabulated against the outcome variables, and difference between classification groups was tested with χ(2) tables and confidence intervals. Slightly older age was found to be linked to excessively crying infants who experienced clinical improvement. However, no apparent link between the clinical effect of chiropractic treatment and a natural decline in crying was found for this group of infants. The findings of this study do not support the assumption that effect of chiropractic treatment of infantile colic is a reflection of the normal cessation of this disorder.

2015-01-01

Introduction Male-to-female (MtF) and female-to-male (FtM) individuals with transsexualism (International Classification of Diseases-10) may differ in core clinical and sociodemographic variables such as age, sexual orientation, marriage and parenthood, school, educational level, and employment. Assessing and understanding the implication of such differences may be a key to developing appropriate and effective treatment and intervention strategies for this group. However, research in the area remains sparse and is often on small populations, making the generalization of results from current studies on individuals diagnosed with transsexualism difficult. Aims (i) To describe and assess key sociodemographic and treatment-related differences between MtF and FtM individuals in a Danish population of individuals diagnosed with transsexualism; (ii) to assess possible implications of such difference, if any, for clinical treatment initiatives for individuals diagnosed with transsexualism. Methods Follow-up of 108 individuals who had permission to undergo sex reassignment surgery (SRS, meaning castration and genital plastic surgery) over a 30-year period from 1978 to 2008 through the Gender Identity Unit in Copenhagen, Denmark. The individuals were identified through Social Security numbers. Clinical and sociodemographic data from medical records were collected. Results The sex ratio was 1.16:1 (MtF : FtM).

Male-to-female (MtF) and female-to-male (FtM) individuals with transsexualism (International Classification of Diseases-10) may differ in core clinical and sociodemographic variables such as age, sexual orientation, marriage and parenthood, school, educational level, and employment. Assessing and understanding the implication of such differences may be a key to developing appropriate and effective treatment and intervention strategies for this group. However, research in the area remains sparse and is often on small populations, making the generalization of results from current studies on individuals diagnosed with transsexualism difficult.

Lifestyle variables may serve as important intermediate factors between psychosocial work environment and health outcomes. Previous studies, focussing on work stress models have shown mixed and weak results in relation to weight change. This study aims to investigate psychosocial factors outside the classical work stress models as potential predictors of change in body mass index (BMI) in a population of health care workers. A cohort study, with three years follow-up, was conducted among Danish health care workers (3982 women and 152 men). Logistic regression analyses examined change in BMI (more than +/- 2 kg/m(2)) as predicted by baseline psychosocial work factors (work pace, workload, quality of leadership, influence at work, meaning of work, predictability, commitment, role clarity, and role conflicts) and five covariates (age, cohabitation, physical work demands, type of work position and seniority). Among women, high role conflicts predicted weight gain, while high role clarity predicted both weight gain and weight loss. Living alone also predicted weight gain among women, while older age decreased the odds of weight gain. High leadership quality predicted weight loss among men. Associations were generally weak, with the exception of quality of leadership, age, and cohabitation. This study of a single occupational group suggested a few new risk factors for weight change outside the traditional work stress models.

Although many genetic and nongenetic factors interact to determine an individual's physical phenotype, there has been limited examination of the contribution of family history of exceptional parental longevity on decline in physical function in aging. The LonGenity study recruited a relatively genetically homogenous cohort of Ashkenazi Jewish adults age 65 and older, who were defined as either offspring of parents with exceptional longevity ([OPEL]: having at least one parent who lived to age 95 or older) or offspring of parents with usual survival ([OPUS]: neither parent survived to age 95). Decline in performance on objective measures of strength (grip strength), balance (unipedal stance), and mobility (gait speed) as well as a composite physical function measure, the Short physical performance battery (SPPB), were compared between the two groups over a median follow-up of 3.2 years, accounting for age, sex, education, and comorbidities. Of the 984 LonGenity participants (mean age 76, 55% women), 448 were OPEL and 536 were OPUS. Compared to OPUS, OPEL had slower decline on measures of unipedal stance (-0.03 log-units/year, p = .026), repeated chair rise (0.13 s/year, p = .020) and SPPB (-0.11 points/year, p = .002). OPEL women had slower decline on chair rise and SPPB scores compared to OPUS women, although OPEL men had slower decline on unipedal stance compared to OPUS men. Our findings provide evidence that variation in late-life decline in physical function is associated with familial longevity, and may vary for men and women. © The Author 2017.

A modular process risk model approach was used to assess health risks associated with Salmonella spp. after consumption of the Danish meatball product (frikadeller) produced with fresh pork in a catering unit. Meatball production and consumption were described as a series of processes (modules), starting from 1.3kg meat pieces through conversion to 70g meatballs, followed by a dose response model to assess the risk of illness from consumption of these meatballs. Changes in bacterial prevalence, concentration, and unit size were modelled within each module. The risk assessment was built using observational data and models that were specific for Salmonella spp. in meatballs produced in the catering sector. Danish meatballs are often pan-fried followed by baking in an oven before consumption, in order to reach the core temperature of 75°C recommended by the Danish Food Safety Authority. However, in practice this terminal heat treatment in the oven may be accidentally omitted. Eleven production scenarios were evaluated with the model, to test the impact of heat treatments and cooling rates at different room temperatures. The risk estimates revealed that a process comprising heat treatment of meatballs to core temperatures higher than 70°C, and subsequent holding at room temperatures lower than 20°C, for no longer than 3.5h, were very effective in Salmonella control. The current Danish Food Safety Authority recommendation of cooking to an internal temperature of 75°C is conservative, at least with respect to Salmonella risk. Survival and growth of Salmonella during cooling of meatballs not heat treated in oven had a significant impact on the risk estimates, and therefore, cooling should be considered a critical step during meatball processing.

Modeling familial British and Danish dementia.

PubMed

Garringer, Holly J; Murrell, Jill; D'Adamio, Luciano; Ghetti, Bernardino; Vidal, Ruben

2010-03-01

Familial British dementia (FBD) and familial Danish dementia (FDD) are two autosomal dominant neurodegenerative diseases caused by mutations in the BRI ( 2 ) gene. FBD and FDD are characterized by widespread cerebral amyloid angiopathy (CAA), parenchymal amyloid deposition, and neurofibrillary tangles. Transgenic mice expressing wild-type and mutant forms of the BRI(2) protein, Bri ( 2 ) knock-in mutant mice, and Bri ( 2 ) gene knock-out mice have been developed. Transgenic mice expressing a human FDD-mutated form of the BRI ( 2 ) gene have partially reproduced the neuropathological lesions observed in FDD. These mice develop extensive CAA, parenchymal amyloid deposition, and neuroinflammation in the central nervous system. These animal models allow the study of the molecular mechanism(s) underlying the neuronal dysfunction in these diseases and allow the development of potential therapeutic approaches for these and related neurodegenerative conditions. In this review, a comprehensive account of the advances in the development of animal models for FBD and FDD and of their relevance to the study of Alzheimer disease is presented.

Danish North Sea Fields consist of several formations (Ekofisk, Tor, and Cromer Knoll) that was started from the age of Paleocene to Miocene. In this study, the integration of seismic and well log data set is carried out to determine the chalk sand distribution in the Danish North Sea field. The integration of seismic and well log data set is performed by using the seismic inversion analysis and seismic multi-attribute. The seismic inversion algorithm, which is used to derive acoustic impedance (AI), is model-based technique. The derived AI is then used as external attributes for the input of multi-attribute analysis. Moreover, the multi-attribute analysis is used to generate the linear and non-linear transformation of among well log properties. In the case of the linear model, selected transformation is conducted by weighting step-wise linear regression (SWR), while for the non-linear model is performed by using probabilistic neural networks (PNN). The estimated porosity, which is resulted by PNN shows better suited to the well log data compared with the results of SWR. This result can be understood since PNN perform non-linear regression so that the relationship between the attribute data and predicted log data can be optimized. The distribution of chalk sand has been successfully identified and characterized by porosity value ranging from 23% up to 30%.

The cultural competence training of healthcare professionals is a key element in ensuring the quality of both the access and delivery of healthcare to increasingly ethnically diverse populations. The aim of this study is to investigate Danish medical teachers' opinions about cultural competence, their willingness to receive training and preparedness to teach cultural competence topics. The survey was sent to medical teachers, clinical teachers and external lecturers who teach in the medical programme at the University of Copenhagen. A total of 1400 medical teachers received the survey, and 199 responded. The response rate is 14%. Data were analysed through descriptive calculations, and answers to open-ended questions were coded using content analysis. Results showed that 82.4% of the informants agreed or strongly agreed that the medical education programme should include training on cultural issues, and 60.3% agreed or strongly agreed that students should be assessed on their cultural competence skills. Regarding preparedness to teach a diverse classroom, 88.4% felt somewhat or very prepared to engage and motivate all students. About 70% were interested in receiving training on cultural competence. Generally, there is interest in and acknowledgement of the importance of cultural competence in Danish medical education among teachers at the University of Copenhagen. This creates an opportunity to implement cultural competence in the medical curriculum, training of teachers and strengthening the diversity sensitivity of the organisation. However, support for this programme by management and the allocation of an appropriate level of resources is a prerequisite to the success of the programme.

The aim was to describe the organization of working hours in the Danish regions according to sex, age and calendar year. Based on the Danish Working Hour Database (DWHD), individuals were classified according to schedules: Permanent day (57.8%), evening (1.7%), or night (1.2%); day/evening (22.0%); day/night (6.6%); evening/night (0.6%); and day/evening/night (10.2%). More men (9.1%) than women (5.9%) worked day/night, whereas more women (10.9%) than men (7.4%) worked day/evening/night. More young than older employees worked day/evening/night, and fewer worked permanent day or night. From 2008 to 2015 we observed a trend towards more employees working permanent day and fewer employees working other schedules. Altogether DWHD provides a strong tool in research on working hours.

Do incident and new subsequent cases of non-melanoma skin cancer registered in a Danish prospective cohort study have different 10-year mortality?

The Danish Gerda Frentz Cohort (GFC) was created for registering all incident and new subsequent cases of non-melanoma skin cancer (NMSC) among patients seen by Danish dermatologists in 1995. We have recently found, in this cohort, a lower 10-year mortality than in the general population in patients with basal cell carcinoma (BCC). Differences in mortality between incident and new subsequent cases, incomplete registration or selection bias may be responsible for this finding. We aimed to quantify differences in mortality between incident and new subsequent cases of NMSC in the GFC and to compare mortality among incident cases recorded in the GFC and those recorded in the Danish Cancer Registry (DCR). We followed 10,830 skin cancer patients and 106,696 age-, gender- and residence-matched population controls through 2006 and computed their cumulative mortality and mortality rate ratio (MRR). One-, 5-, and 10-year cumulative mortality of incident and new subsequent cases of BCC and SCC in the GFC were similar. Likewise, MRR for incident BCC (MRR=0.91; 95% CI 0.84-0.98) and incident SCC (MRR=1.29; 95% CI 1.05-1.56) among patients registered in the GFC were similar to their counterparts in the DCR (MRR=0.96; 95% CI 0.91-1.00 and MRR=1.36; 95% CI 1.22-1.52). Mortality of incident and new subsequent cases of NMSC was similar and thus did not explain the reduced mortality of BCC patients.

Objectives Maternal hyper- and hypothyroidism have been associated with increased risk of adverse pregnancy outcomes, but studies have led to inconsistent results. We aimed to identify children born to mothers with a hospital-recorded diagnosis of thyroid dysfunction in Denmark and to study the association with gestational age at delivery and birth weight of the child. Study Design Population-based cohort study using Danish nationwide registers. All singleton live births in Denmark between January 1, 1978 and December 31, 2006 were identified and stratified by maternal diagnosis of hyper- or hypothyroidism registered in the Danish National Hospital Register before January 1, 2007. Results Maternal first-time diagnosis of thyroid dysfunction before, during or after pregnancy was registered in 32,809 (2.0%) of the singleton live births (n = 1,638,338). Maternal diagnosis of hyperthyroidism (adjusted OR 1.22, 95% CI 1.15-1.30) and hypothyroidism (adjusted OR 1.17, 95% CI 1.08-1.27) were associated with increased risk of preterm birth. Moreover, birth weight in children born to mothers with a diagnosis of hyperthyroidism was lower (adjusted difference −51 g, 95% CI −58 to −43 g) and higher in relation to maternal hypothyroidism (adjusted difference 20 g, 95% CI 10-30 g). Hyperthyroidism was associated with small-for-gestational-age (adjusted OR 1.15, 95% CI 1.10-1.20) and hypothyroidism with large-for-gestational-age children (adjusted OR 1.24, 95% CI 1.17-1.31). Conclusions Based on Danish nationwide registers, both maternal hyper- and hypothyroidism were associated with increased risk of preterm birth. Actual birth weight of the child and birth weight for gestational age were low if the mother had a diagnosis of hyperthyroidism and high if the diagnosis was hypothyroidism. PMID:24783052

Vitamin D status has been associated with cardiometabolic markers even in children, but the associations may be confounded by fat mass and physical activity behaviour. This study investigated associations between vitamin D status and cardiometabolic risk profile, as well as the impact of fat mass and physical activity in Danish 8-11-year-old children, using baseline data from 782 children participating in the Optimal well-being, development and health for Danish children through a healthy New Nordic Diet (OPUS) School Meal Study. We assessed vitamin D status as serum 25-hydroxyvitamin D (25(OH)D) and measured blood pressure, fasting plasma glucose, homoeostasis model of assessment-insulin resistance, plasma lipids, inflammatory markers, anthropometry and fat mass by dual-energy X-ray absorptiometry, and physical activity by 7 d accelerometry during August-November. Mean serum 25(OH)D was 60·8 (sd 18·7) nmol/l. Each 10 mmol/l 25(OH)D increase was associated with lower diastolic blood pressure (-0·3 mmHg, 95 % CI -0·6, -0·0) (P=0·02), total cholesterol (-0·07 mmol/l, 95 % CI -0·10, -0·05), LDL-cholesterol (-0·05 mmol/l, 95 % CI -0·08, -0·03), TAG (-0·02 mmol/l, 95 % CI -0·03, -0·01) (P≤0·001 for all lipids) and lower metabolic syndrome (MetS) score (P=0·01). Adjustment for fat mass index did not change the associations, but the association with blood pressure became borderline significant after adjustment for physical activity (P=0·06). In conclusion, vitamin D status was negatively associated with blood pressure, plasma lipids and a MetS score in Danish school children with low prevalence of vitamin D deficiency, and apart from blood pressure the associations were independent of body fat and physical activity. The potential underlying cause-effect relationship and possible long-term implications should be investigated in randomised controlled trials.

The Danish National Birth Cohort (DNBC) was used to examine pregnancy outcomes among female hairdressers and neurodevelopment in their offspring. A population-based cohort study was conducted of 550 hairdressers and 3216 shop assistants (reference group) by using data from the Danish National Birth Cohort between 1997 and 2003. Information on job characteristics was reported by the women in the first interview (around 17 weeks of gestation). Pregnancy outcomes were obtained by linkage to the national registers. Developmental milestones were reported by the mother at the fourth interview, when the child was approximately 19 months old. Cox regression was applied to analyze fetal loss and congenital malformation. Logistic regression was used to analyze other pregnancy outcomes and developmental milestones. We found no significant differences in fetal loss, multiple births, gender ratio, preterm birth, small-for-gestational age, congenital malformations, or achievement of developmental milestones among the children of hairdressers and shop assistants. The results do not indicate that children of hairdressers in Denmark currently have a high risk of fetal impairment or delayed psychomotor development.

We present measurements of radiocarbon in annual tree rings from the time period 980-1006 Common Era (C.E.), hereby covering the cosmic ray event in 994 C.E. The new radiocarbon record from Danish oak is based on both earlywood and latewood fractions of the tree rings, which makes it possible to study seasonal variations in 14C production. The measurements show a rapid increase of ˜10‰ from 993 to 994 C.E. in latewood, followed by a modest decline and relatively high values over the ensuing ˜10 years. This rapid increase occurs from 994 to 995 C.E. in earlywood, suggesting that the cosmic ray event most likely occurred during the period between April and June 994 C.E. Our new record from Danish oak shows strong agreement with existing Δ14C records from Japan, thus supporting the hypothesis that the 994 C.E. cosmic ray event was uniform throughout the Northern Hemisphere and therefore can be used as an astrochronological tie point to anchor floating chronologies of ancient history.

To assess the relative validity of a semi-quantitative, web-based FFQ completed by female pregnancy planners in the Danish 'Snart Forældre' study. We validated a web-based FFQ based on the FFQ used in the Danish National Birth Cohort against a 4 d food diary (FD) and assessed the relative validity of intakes of foods and nutrients. We compared means and medians of intakes, and calculated Pearson correlation coefficients and de-attenuated coefficients to assess agreement between the two methods. We also calculated the proportion correctly classified based on the same or adjacent quintile of intake and the proportion of grossly misclassified (extreme quintiles). Participants (n 128) in the 'Snart Forældre' study who had completed the web-based FFQ were invited to participate in the validation study. Participants in the 'Snart Forældre' study, in total ninety-seven women aged 20-42 years. Reported intakes of dairy products, vegetables and potatoes were higher in the FFQ compared with the FD, whereas reported intakes of fruit, meat, sugar and beverages were lower in the FFQ than in the FD. Overall the de-attenuated correlation coefficients were acceptable, ranging from 0·33 for energy to 0·93 for vitamin D. The majority of the women were classified in the same or adjacent quintile and few women were misclassified (extreme quintiles). The web-based FFQ performs well for ranking women of reproductive age according to high or low intake of foods and nutrients and, thus, provides a solid basis for investigating associations between diet and fertility.

The aim of this study was to investigate national prevalence, general demographic characteristics and survival of Danish patients with Ehlers-Danlos syndrome (EDS). A population-based cohort study was conducted using a database consisting of the entire Danish population alive at any given time between 1 January 2000 and 31 December 2012, based upon longitudinal Danish national registers. All patients with EDS were identified, and the cohort was described by disease prevalence, basic demographic characteristics, mean age at death and mortality for the observational period of 13 years. The cohort held 1427 unique persons with EDS, giving a national prevalence of 0.02%. The EDS population had a mean ( s . d .) age of 34.9 (18.6) years and comprised 73.9% females and 26.1% males. Of the cohort, 95.9% originated from Denmark and 57% were unmarried. We found that 31.6% of the cohort received state-granted subsidies, of which 77% were in the form of early retirement pension. Regarding educational status, 28.1% of the EDS cohort had completed primary education (⩽10th grade) as their highest educational level, while 71.9% had completed a higher level. During the observation period, 42 patients died, with a mean ( s . d .) age at death of 53.6 (21.7) years. This study confirmed a small national prevalence of patients diagnosed with EDS and showed that the majority of patients diagnosed are female. The EDS cohort had a lower educational level, mean age and life expectancy compared with the background population and showed a predisposition for receiving state-granted subsidies. © The Author 2017.

2016-11-01

Acetaminophen (paracetamol) is the most commonly used pain and fever medication during pregnancy, and recently has been linked to hyperactivity and behavioral problems in children. We examine whether prenatal use of acetaminophen affects children's intelligence quotient (IQ). We studied 1,491 mothers and children enrolled in the Danish National Birth Cohort (DNBC; 1996-2002). Acetaminophen use in pregnancy was prospectively recorded in three telephone interviews. Child IQ was assessed at age 5 with the Wechsler Primary and Preschool Scales of Intelligence-Revised (WPPSI-R) administered by trained psychologists. We employed linear regression analysis, adjusting for maternal IQ and other confounding factors, and assessed interactions between acetaminophen and indications for use. Both maternal fever in pregnancy and acetaminophen use were associated with child IQ. Children born to mothers using acetaminophen without reporting fever scored on average 3.4 points lower (95% confidence interval [CI]: 0.30 to 6.6 points) on performance IQ compared with offspring of mothers who neither experienced fever nor took acetaminophen. Estimated effects for acetaminophen were stronger for first or second trimester use. Children born to mothers reporting fever without using acetaminophen also scored lower on verbal (2.7 points, 95% CI: -0.19, 5.6) and performance IQ (4.3 points, 95% CI: 0.30, 8.3); IQ scores were not affected if mothers with fever used acetaminophen. Maternal acetaminophen use during pregnancy was associated with lower performance IQ in 5-year olds. However, acetaminophen treatment of maternal fever in pregnancy showed an apparent compensatory association with child IQ scores. (See video abstract at http://links.lww.com/EDE/B87.).

Psychological distress is a trans-diagnostic feature of mental suffering closely associated with mental disorders. Kessler's 10-item Psychological Distress Scale (K10), a scale with sound psychometric properties, is widely used in epidemiological studies. To translate and investigate whether K10 is a reliable and valid rating scale for the measurement of psychological distress in a Danish population. The translation was carried out according to official WHO translation guidelines. A sample of 100 subjects was included, 54 patients from the regional Mental Health Service (MHS) and 46 subjects with no psychiatric history. All participants were assessed with a psychiatric diagnostic interview (MINI) and handed out K10. Concurrent validity was assessed by WHO Well-being Index (WHO-5). Correlation matrix analysis was conducted for the full sample and receiver operating characteristic (ROC) curves for discriminating mental health service affiliation. Mean K10 scores differed, with decreasing levels, between inpatients and outpatient in MHS and the subjects with no psychiatric history. Factor analysis confirmed a unidimensional structure, and Cronbach's alpha and Omega showed excellent internal reliability. AUC for the K10 ROC curves showed excellent sensitivity (0.947 [0.900-0.995]), accurately differentiating mental health from non-mental health patients. The Danish K10 has the same strong internal reliability as the original English version, and scores differ between psychiatric patients in outpatient and emergency ward settings. The Danish K10 translation is authorized and freely available for download at https://www.hcp.med.harvard.edu/ncs/k6_scales.php . The utility as an instrument for clinical screening in a mental healthcare setting is supported.

Do follow-on therapeutic substitutes induce price competition between hospital medicines? Evidence from the Danish hospital sector.

PubMed

Hostenkamp, Gisela

2013-06-01

The pricing of follow-on drugs, that offer only limited health benefits over existing therapeutic alternatives, is a recurring health policy debate. This study investigates whether follow-on therapeutic substitutes create price competition between branded hospital medicines. New follow-on drugs and their incumbent therapeutic competitors were identified from Danish sales and product registration data on hospital pharmaceuticals using medically relevant criteria. We examined whether follow-on drugs adopt lower prices than their incumbent competitors, and whether incumbent competitors react to entry of follow-ons through price adjustments using a random intercept panel model. We found no evidence that follow-on drugs adopt lower prices than their incumbent competitors. Furthermore, potentially due to low sample size, we found no evidence that prices for incumbent pioneer products were significantly reduced as a reaction to competition from follow-on drugs. Competition between patented therapeutic substitutes did not seem to increase price competition and containment of pharmaceutical expenditures in the Danish hospital market. Strengthening hospitals' incentives to consider the price of alternative treatment options paired with a more active formulary management may increase price competition between therapeutic substitutes in the Danish hospital sector in the future.

We estimated the rate of compliance with oral bisphosphonates among Danish women and examined its association with health care resource use and cost. Approximately 30 % of Danish females aged >55 who take bisphosphonates are noncompliant, and noncompliance is significantly associated with increased health care resource use and cost. Two objectives of this study were to estimate the rate of oral bisphosphonate compliance among Danish women and to examine the association of noncompliance with health care resource use and cost. Women ≥55 with an index prescription claim for an oral bisphosphonate were identified from Danish national health registries between 2003 and 2008. Compliance was measured as the medication possession ratio (MPR) during the first 12 months post-index. Cost and health care resource use were collected for the following 12 months. Among the 38,234 women meeting the study inclusion criteria, 29.9 % were noncompliant (MPR <70 %). Younger age was associated with higher odds of compliance (OR [95 % CI] 1.22 [1.15-1.29] for ages 55-64 and 1.18 [1.12-1.24] for ages 65-74; reference age group ≥75 years). Rates of all-cause health care resource use were significantly higher in noncompliant subjects: 28.9 versus 23.0 % had inpatient admissions, 16.5 versus 13.0 % had emergency room visits, and 48.7 versus 43.3 % used outpatient services (P < 0.001 for all comparisons). The total mean (SD) all-cause cost per patient (excluding office visits) was €626 (2344) and €4178 (7854), respectively. The mean (SD) osteoporosis-related cost per patient (excluding office visits) was €572 (2085) and €754 (2857) for compliant and non-compliant subjects, respectively. The compliant subjects accrued significantly lower all-cause and OP-related cost than noncompliant subjects, regardless of whether the total cost or medical cost only was considered. Approximately 30 % of Danish females aged 55 or older who take bisphosphonates are noncompliant

Celiac disease, an immunological response triggered by gluten, affects ~1 % of the Western population. Information concerning gluten intake in the general population is scarce. We determined intake of gluten from wheat, barley, rye and oat in the Danish National Survey of Diet and Physical Activity 2005-2008. The study population comprised a random cross-sectional sample of 1494 adults 20-75 years, selected from the Danish Civil Registration System. Protein content in wheat, rye, barley and oat was determined from the National Danish Food Composition Table and multiplied with the amount of cereal used in recipes. Amount of gluten was calculated as amount of cereal protein ×0.80 for wheat and oat, ×0.65 for rye and ×0.50 for barley. Dietary intake was recorded daily during seven consecutive days in pre-coded food diaries with open-answer possibilities. Mean total gluten intake was 10.4 ± 4.4 g/day (10th-90th percentiles; 5.4-16.2 g/day), in men 12.0 ± 4.6 g/day and 9.0 ± 3.4 g/day in women. It was higher among men than among women in all age groups (20-75 years; P < 0.0001); however, this difference was eliminated when adjusting for energy intake. Intake of different gluten sources tended to be higher in men than in women with the exception of gluten from barley. Total gluten intake decreased with increasing age (P < 0.0001) as did gluten intake from wheat (P < 0.0001), whereas intake of gluten from rye (P < 0.0001) and barley (P = 0.001) increased with increasing age, also when adjusted for energy intake or body weight. This study presents representative population-based data on gluten intake in Danish adults. Total gluten intake decreased with increasing age.

Pelvic pain during pregnancy is a common ailment, and the disease is a major cause of sickness absence during pregnancy. It is plausible that occupational lifting may be a risk factor of pelvic pain during pregnancy, but no previous studies have examined this specific exposure. The aim of this study was to examine the association between occupational lifting and pelvic pain during pregnancy. The study comprised 50 143 pregnant women, enrolled in the Danish National Birth Cohort in the period from 1996-2002. During pregnancy, the women provided information on occupational lifting (weight load and daily frequency), and six months post partum on pelvic pain. Adjusted odds ratios for pelvic pain during pregnancy according to occupational lifting were calculated by logistic regression. Any self-reported occupational lifting (>1 time/day and loads weighing >10 kg) was associated with an increased risk of pelvic pain during pregnancy as compared to no such lifting. A confounder-adjusted exposure-response relation was observed between self-reported total loads lifted and pelvic pain during pregnancy. Daily lifting of both medium (11-20 kg) and heavy loads (>20 kg) were associated with increased risk, and the highest risk was observed among women who lifted heavy loads independent of exposure to medium loads. Occupational lifting may increase the risk of pelvic pain during pregnancy.

In spite of decades of very active labor market policies, 25% of Denmark's population in the working ages are still out-of-work. The aim of this study was to investigate whether that is due to consistent or even increasing prevalence of ill health. For the period of 2002-2011, we investigated if i) the prevalence of four chronic diseases (cardiovascular disease, diabetes, cancer and mental disorders) among those out-of-work had changed, ii) the occurrence of new cases of those diseases were higher among those who were already out-of-work, or iii) if non-health-related benefits were disproportionately given to individuals recently diagnosed with a disease compared to those without disease. The study was register-based and comprised all Danish residents aged 20-60. During the study period, the prevalence of cardiovascular diseases and mental disorders increased among both employed and non-employed people. The increased prevalence for mental disorder was particularly high among people receiving means-tested benefits. Disease incidence was higher among people outside rather than inside the labor market, especially for mental disorders. Employed people with incident diseases had an unsurprisingly increased risk of leaving the labor market. However, a high proportion of people with incident mental disorders received low level means-tested benefits in the three years following this diagnosis, which is concerning. Men treated for mental disorders in 2006 had high excess probability of receiving a cash-benefit, OR = 4.83 (4.53-5.14) for the period 2007-2010. The estimates were similar for women.

Recent changes in Danish law on drugs and drug offences.

PubMed

Jepsen, J; Laursen, L

1998-09-01

The article recounts changes in Danish Drug Law and Enforcement since the beginning of the 1990s and relates them to general trends in Danish criminal policy during the period. In addition to the implementation of EU directives, e.g. on money laundering and growth hormones, legislation has been passed to curb conspicuous dealing of drugs in the streets of Copenhagen. This part of the legislation is seen as a reaction to public fears and reactions to visible aliens dealing in drugs in a conspicuous way, albeit in minor quantities. The legal changes imply a considerable rise in penalties for repeated dealings in minor quantities and easier access to deportation of aliens. The latter has been criticized as potential violation of the human rights of aliens. This and other recent changes in criminal law and related legislation is seen as an indication of politicians' concerns with voters' anxieties, possibly at the edge of moral panics.

Objective To evaluate the association between chocolate intake and incident clinically apparent atrial fibrillation or flutter (AF).. Methods The Danish Diet, Cancer and Health Study is a large population-based prospective cohort study. The present study is based on 55,502 participants (26,400 men and 29,102 women) aged 50–64 years who had provided information on chocolate intake at baseline. Incident cases of AF were ascertained by linkage with nationwide registries. Results During a median of 13.5 years, there were 3,346 cases of AF. Compared with chocolate intake less than once per month, the rate of AF was lower for people consuming 1–3 servings/month (Hazard Ratio [HR]= 0.90, 95% confidence interval [CI] 0.82–0.98), 1 serving/week (HR= 0.83, 95% CI 0.74–0.92), 2–6 servings/week (HR= 0.80, 95% CI 0.71–0.91) and 1 servings/day (HR= 0.84, 95 %CI 0.65–1.09; p-linear trend<0.0001), with similar results for men and women. Conclusions Accumulating evidence indicates that moderate chocolate intake may be inversely associated with AF risk, though residual confounding cannot be ruled out. PMID:28536115

Vestibular schwannomas grow in the region within the brain where most of the energy by radiofrequency electromagnetic fields from using mobile phones is absorbed. The authors used 2 Danish nationwide cohort studies, one a study of all adult Danes subscribing for a mobile phone in 1995 or earlier and one on sociodemographic factors and cancer risk, and followed subjects included in both cohorts for occurrence of vestibular schwannoma up to 2006 inclusively. In this study including 2.9 million subjects, a long-term mobile phone subscription of ≥11 years was not related to an increased vestibular schwannoma risk in men (relative risk estimate = 0.87, 95% confidence interval: 0.52, 1.46), and no vestibular schwannoma cases among long-term subscribers occurred in women versus 1.6 expected. Vestibular schwannomas did not occur more often on the right side of the head, although the majority of Danes reported holding their mobile phone to the right ear. Vestibular schwannomas in long-term male subscribers were not of larger size than expected. Overall, no evidence was found that mobile phone use is related to the risk of vestibular schwannoma. Because of the usually slow growth of vestibular schwannoma and possible diagnostic delay, further surveillance is indicated.

The aim of this study was to identify who is at risk for long-term sickness absence according to occupation, gender, education, age, business sector, agency size and ownership. The study is based on a sample of 5357 employees aged 18-69, interviewed in 2000. The cohort was followed up in a national register from January 1st 2001 to June 30th 2003, to identify cases with sickness absences that exceeded 8 weeks. During follow-up 486 persons (9.1%) experienced one or more periods of absence that exceeded 8 weeks. Higher risk of long-term sickness absence was associated with gender, age, educational level, and the municipal employment sector. Kindergarten teachers and people employed in day care, health care, janitorial work, food preparation, and unskilled workers were at greatest risk. Managers, computer professionals, technicians and designers, and professionals had lower risks. The health care and social service sectors were also in the high risk category, whereas the private administration sector had a lower risk. The study identifies specific occupational target populations and documents the need to perform job-specific research and tailor interventions if the intended policy of decreasing long-term sickness absence within the Danish labour market is to be realized.

It is currently unknown if school-based social norms interventions are effective in preventing harmful alcohol consumption and other drug use among adolescents in Denmark. This paper describes the social norms-based programme The GOOD life and the design of a cluster-randomized controlled trial to test its effectiveness. The intervention The GOOD life is composed of three social norms components representing three different communication channels, namely face-to-face communication (normative feedback session), print communication (posters) and interactive media (web application). The intervention period of 8 weeks is preceded and followed by data collection, with the follow-up taking place 3 months after baseline. Public schools in the Region of Southern Denmark with grades 8 and 9 are invited to participate in the study and participating schools are randomly allocated to either intervention or control schools. The aim is to recruit a total of 39 schools and a sample of 1.400 pupils for the trial. An online questionnaire is conducted to examine the use of alcohol, tobacco and marijuana as well as the perceived frequency of use among peers of their own grade, which is measured before and after the intervention. Baseline data is used to develop social norms messages which are included in the three intervention components. Primary outcomes are binge drinking (more than 5 units at one occasion) and perceived frequency of binge drinking among peers, while smoking, marijuana use and alcohol-related harm will be assessed as secondary outcomes. The GOOD life study will provide necessary insights on descriptive and injunctive norms regarding alcohol and other drug use among Danish adolescents. In addition, it will provide new knowledge and insight on the feasibility, implementation context and effectiveness of a newly developed social norms intervention in the Danish school context.

The Danish health care system: it ain't broke... so don't fix it.

PubMed

Mooney, Gavin

2002-02-01

The organisation and financing of the Danish health care system was evaluated within a framework of analysis of strengths, weaknesses, opportunities and threats (a SWOT analysis) by a panel of five members with a background in health economics. The evaluation was based on reading an extensive amount of selected documents and literature on the Danish health care system, and a 1 week-visit to health care authorities, providers and key persons. This paper includes the main findings by one of the panel members. The international competition 'wave' passed by Denmark, and the Danish might rightly say 'thank goodness'. Funding is very largely public and there is a single dominant authority, i.e. the county, which makes planning easier. Low levels of patient payments and the smaller size of the private sector reflect Danish 'solidarity' and promote equity. Planning is good. Exceptions to this are the over-concern with hospital waiting lists and the flirting with DRG based funding. Greater investment in planning approaches would make the system yet better. The GP blended remuneration system with capitation and fee for service is a major strength. The fact that the system has such potential for technical and allocative efficiency and also equity but is not fully exploited suggests the need for more investment in health services research. While there is scope for improving the health care system in Denmark, the rest of the world has as much to learn from the Danes as the Danes have from the rest of the world.

The Value of Open Geographical Data - The Danish Case

Good basic data for everyone is part of the common public-sector digitization strategy for 2011 to 2015. The vision is that basic data is to be the high-quality common foundation for public sector administration; efficiently updated at one place, and used by everyone - including the private sector. Open basic data will benefit public-sector efficiency as well as innovation and value creation by Danish society in general. With basic data as a new digital raw material, commercial products can be developed and public information and services can be improved, providing for greater insight and stronger democracy. On the first of January 2013 Denmark released this digital raw material. As a general rule, all basic data is to be made freely available to all public authorities, private businesses and individuals. This makes basic data a common digital resource, which can be exploited freely for commercial as well as non-commercial purposes. A positive business case contributed in convincing Danish politicians to approve the basic data program. Once the initiatives have been fully implemented, the revenues for society are expected to be approx. DKK 800 million annually. Private-sector revenues will be up to DKK half a billion annually, and it is expected that e.g. the real estate, insurance, financial, and telecom sectors, as well as GPS (sat-nav) manufacturers, public companies and entrepreneurs will be among those to benefit hugely from the initiatives. The financial gain for the private sector of open geographical data alone is expected to be approx. 100 million DKK annually. As part of the Basic data program The Danish Geodata Agency (Ministry of the Environment) gave free access to all topographic data, cadastral maps and Digital Elevation Model on Jan. 1st, 2013. The Danish Geodata Agency has decided to measure the effect of the open geographic data in the public sector (efficiency) and in the private sector (growth). The effect will be measured by using reference

Interstitial lung diseases (ILDs) form a heterogeneous group of rare diseases characterised by varying degrees of pulmonary inflammation and fibrosis. We hypothesised that IPF and unclassifiable ILD were common in a Danish ILD cohort and that prognostic factors based on disease characteristics and comorbidities could be identified The aims of the PhD study were to describe the demographics of ILD in Central Denmark, to characterise the distribution of ILD diagnoses, and to assess prognostic factors in IPF and unclassifiable ILD. The study is based on a cohort of 431 ILD patients referred to our department during a 6-year period. All ILD diagnoses were re-evaluated according to current diagnostic criteria. Patients were followed from the time of first visit on suspicion of an ILD to the last visit to the centre, death, transplantation, or discharge from follow-up. The incidence of ILD was 4.1 per 100,000 inhabitants, and the incidence of IPF was 1.3 per 100,000 inhabitants in Central Den-mark. The most frequently occurring ILDs were IPF (28%), unclassifiable ILDs (extensive fibrotic disease and other unclassifiable ILDs) (24%), connective tissue disease-related ILD (14%), hyper-sensitivity pneumonitis (7%) and NSIP (7%). Cardiovascular dis-ease was present in 21% of the patients. The presence of cardio-vascular disease at the time of IPF diagnosis did not lead to increased mortality, whereas cardiovascular disease diagnosed during the course of IPF was a statistically significant predictor of mortality. Our study also showed that diabetes and concomitant anticoagulant therapy were associated with worse outcome in IPF, and that a simple HRCT scoring system could be used in the prediction of outcome in fibrotic ILDs. The study of unclassifiable ILD revealed two disease categories: one group characterised by extensive fibrotic disease and one characterised by more inflammatory features. The latter group was characterised by younger age and significantly better

The purpose of the present study was to describe early feeding patterns in Danish infants. A self-administered questionnaire was sent to 7113 mothers of newborns in the western part of Denmark approximately 6 months postpartum. A total of 5127 mothers (72%) returned the questionnaire and 4526 (88%) of the responding mothers provided valid answers to questions on infant nutrition. Breastfeeding was initiated after birth by 97%. At the ages of 2, 4 and 6 months, 68%, 55% and 7% of the infants, respectively, were fully breastfed, i.e. they received mother's milk only. Full breastfeeding at 4 months was for infants significantly associated with higher birth weight, longer gestational age and singleton birth; for mothers it was associated with older ages, higher educational level, lower BMI and multiparity. During the first weeks, 14% of the infants were introduced to formula and this proportion increased to 32%, 43% and 74% at 2, 4 and 6 months, respectively. Only 20% of the infants never received formula during the first 6 months of life. Time for introduction of solid food was associated with breastfeeding status. At 4 months, 3% of the previously fully breastfed infants were introduced to solid food, 12% of the partially breastfed and 17% of the non-breastfed. At 6 months, 87% of the infants had been introduced to solid food. The majority of Danish mothers introduced infants to solid food between 4 and six months, and did not exclusively breastfeed until 6 months, as recommended by WHO. © 2015 the Nordic Societies of Public Health.

Seasonal Variation of Dystocia in a Large Danish Cohort

Background Dystocia is one of the most frequent causes of cesarean delivery in nulliparous women. Despite this, its causes are largely unknown. Vitamin D receptor (VDR) has been found in the myometrium. Thus, it is possible that vitamin D affects the contractility of the myometrium and may be involved in the pathogenesis of dystocia. Seasonal variation of dystocia in areas with distinct seasonal variation in sunlight exposure, like Denmark, could imply that vitamin D may play a role. This study examined whether there was seasonal variation in the incidence of dystocia in a Danish population. Method We used information from a cohort of 34,261 nulliparous women with singleton pregnancies, spontaneous onset of labor between 37 and 42 completed gestational weeks, and vertex fetal presentation. All women gave birth between 1992 and 2010 at the Department of Obstetrics and Gynecology, Aarhus University Hospital, Skejby. Logistic regression combined with cubic spline was used to estimate the seasonal variation for each outcome after adjusting for calendar time. Results No evidence for seasonal variation was found for any of the outcomes: acute cesarean delivery due to dystocia (p = 0.44); instrumental vaginal delivery due to dystocia (p = 0.69); oxytocin augmentation due to dystocia (p = 0.46); and overall dystocia (p = 0.91). Conclusion No seasonal variation in the incidence of dystocia was observed in a large cohort of Danish women. This may reflect no association between vitamin D and dystocia, or alternatively that other factors with seasonal variation and influence on the occurrence of dystocia attenuate such an association.

Different Bacillus Calmette-Guerin (BCG) vaccine strains may have different non-specific effects. We assessed the effect of two BCG strains (Danish and Russian) on childhood morbidity and BCG scarification in Guinea-Bissau. During 2011-2013, infants in the Bandim Health Project's urban study area received the Danish or Russian BCG in a natural experiment. Health center consultations were registered at point of care and scar status and size at age 4½ months. We assessed the effect of strain on consultation rates between vaccination and age 45days in Cox proportional hazards models. Scar prevalence and size were compared using binomial regression and ranksum tests. Among 1206 children, 18% received Danish BCG (n=215) and 82% Russian BCG (n=991). The adjusted hazard ratio (aHR) for consultations was 0.94 (95% CI 0.60-1.46) for Danish BCG compared with Russian BCG. Girls vaccinated with Danish BCG tended to have lower consultation rates compared with girls vaccinated with Russian BCG (aHR 0.56 (0.25-1.24)), whereas the effect was opposite for boys (aHR 1.24 (0.74-2.11)), p=0.09. Children vaccinated with Danish BCG were more likely to develop a scar (97%) than children vaccinated with Russian BCG (87%), the relative risk (RR) being 1.11 (1.06-1.16). The effect was stronger in girls, and BCG scar size was larger among infants vaccinated with the Danish strain. BCG strain influences scar prevalence and scar size, and may have sex differential effects on morbidity. BCG strains are currently used interchangeably, but BCG scarring has been linked to subsequent survival. Hence, more research into the health effects of different BCG strains is warranted. Small adjustments of BCG production could potentially lower childhood morbidity and mortality at low cost. Copyright © 2016 Elsevier Ltd. All rights reserved.

Prayer and meditation among Danish first time mothers-a questionnaire study.

Mothers' existential dimensions in the transition to motherhood have not been described thoroughly. They might experience disruption and new perspectives in existential ways and this may especially be the case in preterm birth. The aim of this study was twofold. First we investigated the existential dimension of motherhood transition in a secularized context, through practices of prayer and meditation. Second we described the relationship between time of birth (term/preterm) and the prayer/meditation practices of the mothers. Data were gathered from a nationwide questionnaire survey among first time mothers conducted during the summer 2011. All Danish women who gave birth before the 32(nd) pregnancy week (n = 255), and double the number of mothers who gave birth at full term (n = 658) in 2010 were included (total n = 913). The questionnaire consisted of 46 overall items categorized in seven sections, which independently cover important aspects of existential meaning-making related to becoming a mother. The respondent rate was 57% (n = 517). Moments of praying or meditation 6-18 months post partum were reported by 65%, and mothers who responded affirmatively, practiced prayer (n = 286) more than meditation (n = 89), p < 0,001. We did not observe differences in affirmative responses to prayer or meditation between mothers of full term or preterm born children, not even after controlling for perinatal or post partum loss, mode of birth, age, status of cohabiting or education. In this explorative study we found specific practices of existential meaning-making through prayer and/or meditation among first time mothers, living in a very secularized context. Yet we know only little about character or importance of these practices among mothers, and hardly anything about existential meaning-making among new fathers. Hence the implications of meaning-making practices related to other dimensions of health are difficult to address in a qualified way

The aim of this study was to examine whether there was a difference between clinical nurses who were research-active, and clinical nurses who were nonresearch-active in utilization of research. A further aim was to identify the most significant barriers faced by a group of Danish clinical nurses in their use of research. Discrepancy between the improved quality of research results and the lack of implementing them was the starting point for a series of studies which showed the types of barriers clinical nurses found especially cumbersome when applying the research results of other researchers. This study investigates whether the clinical nurses' own engagement in research had any impact on their perception of research utilization. The study had an exploratory and descriptive design. Seventy-nine Danish clinical nurses participated and semi-structured interviewing was used as the research method. There was a statistically significant difference between the research-active and nonresearch-active nurses on various variables. The study showed that, to a larger extent, research-active nurses used evidence-based knowledge and were generally more internationally orientated. Furthermore, two important barriers for research utilization were identified by all 79 clinical nurses included in the study, i.e. 90% of the nurses explained that the quantity of research results was overwhelming, and 75% of them found that they were unable to evaluate the quality of the research. Clinical nurses, who were research-active themselves, experienced more success in overcoming some of the barriers, which existed in applying research to practice. The research potential found amongst clinical nurses in Denmark needed to be further supported through training and guidance in research methodology, establishing introductory stipends and part-time research positions. By doing so, some of the barriers affecting research utilization and the so-called theory-practice gap might be reduced. Further

Purpose Measuring and developing a safe culture in health care is a focus point in creating highly reliable organizations being successful in avoiding patient safety incidents where these could normally be expected. Questionnaires can be used to capture a snapshot of an employee’s perceptions of patient safety culture. A commonly used instrument to measure safety climate is the Safety Attitudes Questionnaire (SAQ). The purpose of this study was to adapt the SAQ for use in Danish hospitals, assess its construct validity and reliability, and present benchmark data. Materials and methods The SAQ was translated and adapted for the Danish setting (SAQ-DK). The SAQ-DK was distributed to 1,263 staff members from 31 in- and outpatient units (clinical areas) across five somatic and one psychiatric hospitals through meeting administration, hand delivery, and mailing. Construct validity and reliability were tested in a cross-sectional study. Goodness-of-fit indices from confirmatory factor analysis were reported along with inter-item correlations, Cronbach’s alpha (α), and item and subscale scores. Results Participation was 73.2% (N=925) of invited health care workers. Goodness-of-fit indices from the confirmatory factor analysis showed: c2=1496.76, P<0.001, CFI 0.901, RMSEA (90% CI) 0.053 (0.050–0056), Probability RMSEA (p close)=0.057. Inter-scale correlations between the factors showed moderate-to-high correlations. The scale stress recognition had significant negative correlations with each of the other scales. Questionnaire reliability was high, (α=0.89), and scale reliability ranged from α=0.70 to α=0.86 for the six scales. Proportions of participants with a positive attitude to each of the six SAQ scales did not differ between the somatic and psychiatric health care staff. Substantial variability at the unit level in all six scale mean scores was found within the somatic and the psychiatric samples. Conclusion SAQ-DK showed good construct validity and

Communication between health professional and patient is central for treatment and patient safety in the health-care system. This systematic review examines the last ten years of specialist literature concerning interpretation in the Danish health-care system. Structural search in two databases, screening of references and recommended literature from two scientists led to identification of seven relevant articles. The review showed that professional interpreters were not used consistently when needed. Family members were also used as interpreters. These results were supported by international investigations.

Background Intermittent monitoring of fruit and vegetable intake at the population level is essential for the evaluation and planning of national dietary interventions. Yet, only a limited number of studies on time trends in fruit and vegetable intake among children and adolescents have been published internationally. In Denmark, national comprehensive campaigns to enhance fruit and vegetable consumption were initiated in 2001. This paper describes secular trends in fruit intake among Danish adolescents by six comparable school surveys from 1988 to 2006. The paper demonstrates and discusses the consequences of measurement changes introduced in long-term trend analyses. Methods We used Danish data from the international Health Behaviour in School-aged Children (HBSC) study collected in 1988, 1991, 1994, 1998, 2002 and 2006. Analyses were conducted on comparable questionnaire-based data from students aged 11, 13 and 15 total (n = 23,871) from a random sample of schools. Data on fruit intake were measured by a food frequency questionnaire. Due to changes in number of response categories beween surveys, different cut-points were analysed. Results The prevalence of students eating fruit at least once daily ranged from 78.3% among 13-year-old girls in 1988 to 17.3% among 15-year-old boys in 2002. Based on the six data collections, analyses of trends showed a significant decrease in prevalence of students eating fruit at least once daily from 1988 to 2002 (all p-values < 0.0001). In all age and gender groups, a significant increase in intake occurred between 2002 and 2006 (all p-values < 0.0065). Analyses of alternative cut-points revealed similar results. Conclusion Fruit consumption among Danish schoolchildren decreased from 1988 to 2002 with an increase since 2002. We suggest that the increase may be attributable to a nation-wide initiative conducted in Denmark since 2001 to increase the intake of fruit and vegetables in the population. Still, the results imply that a

The recently discovered human parvovirus 4 (PARV4) is found most frequently in injection drug users, HIV-positive patients, and in haemophiliacs. Studies from Ghana report the finding of PARV4 in plasma from 2 to 12% of children without acute infection, and in nasal secretions and faecal samples. Studies of PARV4 in children from industrialized countries are few. We aimed to describe the occurrence of PARV4 in a population-based birth cohort of 228 Danish mothers and their healthy children who previously participated in a study of respiratory tract infections in infancy. Children were included over a whole calendar year and were monitored through monthly home visits through the first year of life. Plasma samples for the present study were available from 228 mothers, 176 newborns, and 202 12-months-old children. All samples were analysed for the presence of PARV4 antibodies by enzyme immunoassay, and samples with detectable antibodies were in addition studied by real-time PCR. One (0.4%) of 228 mothers had PARV4 IgG exceeding the cut-off absorbance level and another had borderline IgG reactivity. No mother among these two had an acute infection, as they were IgM and PARV4 DNA negative. All blood samples from newborns and one-year-old children had IgG and IgM reactivity below cut-off. PARV4 is rare in Danish mothers and infants. Further studies are needed, in both rural and urban settings, to investigate the epidemiology and clinical significance of this novel human parvovirus.

Nursing was established in Denmark as a scholarly tradition in the late nineteen eighties, and ethnography was a preferred method. No critical review has yet summarised accomplishments and gaps and pointing at directions for the future methodological development and research herein. This review critically examines the current state of the use of ethnographic methodology in the body of knowledge from Danish nursing scholars. We performed a systematic literature search in relevant databases from 2003 to 2016. The studies included were critically appraised by all authors for methodological robustness using the ten-item instrument QARI from Joanna Briggs Institute. Two hundred and eight studies met our inclusion criteria and 45 papers were included; the critical appraisal gave evidence of studies with certain robustness, except for the first question concerning the congruity between the papers philosophical perspective and methodology and the seventh question concerning reflections about the influence of the researcher on the study and vice versa. In most studies (n = 34), study aims and arguments for selecting ethnographic research are presented. Additionally, method sections in many studies illustrated that ethnographical methodology is nurtured by references such as Hammersley and Atkinson or Spradley. Evidence exists that Danish nursing scholars' body of knowledge nurtures the ethnographic methodology mainly by the same few authors; however, whether this is an expression of a deliberate strategy or malnutrition in the form of lack of knowledge of other methodological options appears yet unanswered. © 2017 Nordic College of Caring Science.

The biochemical methane potential (BMP) is an essential parameter when using first order decay (FOD) landfill gas (LFG) generation models to estimate methane (CH4) generation from landfills. Different categories of waste (mixed, shredder and sludge waste) with a low-organic content and temporarily stored combustible waste were sampled from four Danish landfills. The waste was characterized in terms of physical characteristics (TS, VS, TC and TOC) and the BMP was analyzed in batch tests. The experiment was set up in triplicate, including blank and control tests. Waste samples were incubated at 55°C for more than 60 days, with continuous monitoring of the cumulative CH4 generation. Results showed that samples of mixed waste and shredder waste had similar BMP results, which was in the range of 5.4-9.1 kg CH4/ton waste (wet weight) on average. As a calculated consequence, their degradable organic carbon content (DOCC) was in the range of 0.44-0.70% of total weight (wet waste). Numeric values of both parameters were much lower than values of traditional municipal solid waste (MSW), as well as default numeric values in current FOD models. The sludge waste and temporarily stored combustible waste showed BMP values of 51.8-69.6 and 106.6-117.3 kg CH4/ton waste on average, respectively, and DOCC values of 3.84-5.12% and 7.96-8.74% of total weight. The same category of waste from different Danish landfills did not show significant variation. This research studied the BMP of Danish low-organic waste for the first time, which is important and valuable for using current FOD LFG generation models to estimate realistic CH4 emissions from modern landfills receiving low-organic waste.

The first birth cohorts of women offered human papillomavirus (HPV) vaccination as girls are now entering cervical screening. However, there is no international consensus on how to screen HPV vaccinated women. These women are better protected against cervical cancer and could therefore be offered less intensive screening. Primary HPV testing is more sensitive than cytology, allowing for a longer screening interval. The aim of Trial23 is to investigate if primary HPV testing with cytology triage of HPV positive samples is a reasonable screening scheme for women offered HPV vaccination as girls. Trial23 is a method study embedded in the existing cervical screening programme in four out of five Danish regions. Without affecting the screening programme, women born in 1994 are randomised to present screening with liquid-based cytology every third year (present programme arm) or present screening plus an HPV test (HPV arm). The study started 1 February 2017 and will run over three screening rounds corresponding to 7-8 years. The primary endpoint is cervical intraepithelial neoplasia grade 3 or above. The trial is undertaken as a non-inferiority study including intention-to-treat and per-protocol analyses. The potential effect of primary HPV screening with a 6-year interval will be calculated from the observed data. The study protocol has been submitted to the ethical committee and deemed a method study. All women are screened according to routine guidelines. The study will contribute new evidence on the future screening of HPV vaccinated birth cohorts of women. All results will be published in open-access journal.

2016-01-01

Introduction: Despite many initiatives to improve coordination of patient pathways and intersectoral cooperation, Danish health care is still fragmented, lacking intra- and interorganisational integration. This study explores barriers to and facilitators of interorganisational integration as perceived by healthcare professionals caring for patients with chronic obstructive pulmonary disease within the Danish healthcare system. Methods: Seven focus groups were conducted in January through July 2014 with 21 informants from general practice, local healthcare centres and a pulmonary department at a university hospital in the Capital Region of Denmark. Results and discussion: Our results can be grouped into five influencing areas for interorganisational integration: communication/information transfer, committed leadership, patient engagement, the role and competencies of the general practitioner and organisational culture. Proposed solutions to barriers in each area hold the potential to improve care integration as experienced by individuals responsible for supporting and facilitating it. Barriers and facilitators to integrating care relate to clinical, professional, functional and normative integration. Especially, clinical, functional and normative integration seems fundamental to developing integrated care in practice from the perspective of healthcare professionals. PMID:27616948

The Danish Nonmelanoma Skin Cancer Dermatology Database was established in 2008. The aim of this database was to collect data on nonmelanoma skin cancer (NMSC) treatment and improve its treatment in Denmark. NMSC is the most common malignancy in the western countries and represents a significant challenge in terms of public health management and health care costs. However, high-quality epidemiological and treatment data on NMSC are sparse. The NMSC database includes patients with the following skin tumors: basal cell carcinoma (BCC), squamous cell carcinoma, Bowen's disease, and keratoacanthoma diagnosed by the participating office-based dermatologists in Denmark. Clinical and histological diagnoses, BCC subtype, localization, size, skin cancer history, skin phototype, and evidence of metastases and treatment modality are the main variables in the NMSC database. Information on recurrence, cosmetic results, and complications are registered at two follow-up visits at 3 months (between 0 and 6 months) and 12 months (between 6 and 15 months) after treatment. In 2014, 11,522 patients with 17,575 tumors were registered in the database. Of tumors with a histological diagnosis, 13,571 were BCCs, 840 squamous cell carcinomas, 504 Bowen's disease, and 173 keratoakanthomas. The NMSC database encompasses detailed information on the type of tumor, a variety of prognostic factors, treatment modalities, and outcomes after treatment. The database has revealed that overall, the quality of care of NMSC in Danish dermatological clinics is high, and the database provides the necessary data for continuous quality assurance.

To determine the impact of the European Union's Clinical Trials Directive on the number of academic drug trials carried out in Denmark. Retrospective review of applications for drug trials to the Danish Medicines Agency, 1993-2006. Applications for drug trials for alternate years were classified as academic or commercial trials. A random subset of academic trials was reviewed for number of participants in and intended monitoring of the trials. Academic and commercial drug trials showed an identical steady decline from 1993 to 2006 and no noticeable change after 2004 when good clinical practice became mandatory for academic trials. The Clinical Trials Directive introduced in May 2004 to ensure good clinical practice for academic drug trials was not associated with a decline in research activity in Denmark; presumably because good clinical practice units had already been in place in Danish universities since 1999. With such an infrastructure academic researchers can do drug trials under the same regulations as drug companies.

Aims The diabetogenic effect of diuretics, as well as the indication for prescribing them, may impact on fetal growth. We analysed whether the purchase of prescription drugs for diuretics during pregnancy was associated with measures of fetal growth. Methods During 1991–98 all women who purchased prescription drugs for diuretics during pregnancy were identified in the Northern Jutland Prescription Database (NJDP), Denmark, and in the Medicines Monitoring Unit's Database (MEMO), Scotland. Information on birth weight and gestational age was obtained from the Danish Birth Registry, the Danish Hospital Discharge Registry and the Scottish Tayside Neonatal Database. Information on diabetes, hypertension and prepregnancy weight were obtained by hospital record review in a sample of women in the Danish cohort. Women who did not purchase prescription diuretics during pregnancy were used as a reference group in both cohorts. Results Danish women who purchased prescription loop diuretics during pregnancy gave birth to infants with higher birth weights than women who did not use diuretics; mean difference 104.7 g (95% CI; 2.6, 206.9). However, the high prevalence of diabetes (10.3%) among Danish women who purchased prescription loop diuretics during pregnancy might explain this result. Both the Danish and the Scottish women who purchased prescription diuretics during their pregnancy were at increased risk of preterm delivery (< 37 completed weeks); ORs: 1.8 (CI; 1.2, 2.7)NJDP, 1.9 (CI; 0.9, 4.3)MEMO. The proportion of hypertension among women who purchased prescription thiazides was 15.8%, and the risk of having an infant with a birth weight (BW) < 2500 g was increased; ORs: 2.6 (CI; 1.4, 5.0)NJDP, 2.4 (CI; 0.8, 7.8)MEMO. Conclusions Prescribing diuretics during pregnancy was associated with differences in birth weight and incidence of preterm delivery. Confounding by indication may explain the findings.

Lytje, Martin

2018-04-01

This study explored how Danish students experienced returning to school following parental bereavement. Eighteen focus group interviews were conducted with 39 participants aged 9 to 17. All participants had experienced the loss of a primary caregiver. Data collection was divided into two phases. In Phase I, 22 participants from four grief groups were interviewed 4 times over the course of a year. During Phase II, confirmatory focus groups were undertaken with the 17 participants. This article explores the findings related to ideas and suggestions made by the students about how the Danish school response could be improved to better meet their needs. The presentation of data is divided into seven themes, which are: Desired school response; Desired support from teachers; Desired boundaries between students and teachers; Desired collaboration; Desired support from peers; Desired rules and structure, and; Desires related to gifts and rituals. Study findings indicate that most students want to be included and have a say when the school plans how to respond to their loss. Students further highlight a need for teacher support when having to reconnect with the class; a need for set rules in relation to leaving the class when feeling sad, and; a need for schools to see the loss as a life-changing event, and grief as something that does not simply disappear after a few months. The article concludes by discussing the ways in which the recommendations provided by the participants can be incorporated into a modern revision of Danish school bereavement response plans.

Methane (CH₄) generated from low-organic waste degradation at four Danish landfills was estimated by three first-order decay (FOD) landfill gas (LFG) generation models (LandGEM, IPCC, and Afvalzorg). Actual waste data from Danish landfills were applied to fit model (IPCC and Afvalzorg) required categories. In general, the single-phase model, LandGEM, significantly overestimated CH₄generation, because it applied too high default values for key parameters to handle low-organic waste scenarios. The key parameters were biochemical CH₄potential (BMP) and CH₄generation rate constant (k-value). In comparison to the IPCC model, the Afvalzorg model was more suitable for estimating CH₄generation at Danish landfills, because it defined more proper waste categories rather than traditional municipal solid waste (MSW) fractions. Moreover, the Afvalzorg model could better show the influence of not only the total disposed waste amount, but also various waste categories. By using laboratory-determined BMPs and k-values for shredder, sludge, mixed bulky waste, and street-cleaning waste, the Afvalzorg model was revised. The revised model estimated smaller cumulative CH₄generation results at the four Danish landfills (from the start of disposal until 2020 and until 2100). Through a CH₄mass balance approach, fugitive CH₄emissions from whole sites and a specific cell for shredder waste were aggregated based on the revised Afvalzorg model outcomes. Aggregated results were in good agreement with field measurements, indicating that the revised Afvalzorg model could provide practical and accurate estimation for Danish LFG emissions. This study is valuable for both researchers and engineers aiming to predict, control, and mitigate fugitive CH₄emissions from landfills receiving low-organic waste. Landfill operators use the first-order decay (FOD) models to estimate methane (CH₄) generation. A single-phase model (LandGEM) and a traditional model (IPCC) could result in

Human biomonitoring (HBM) is an important tool, increasingly used for measuring true levels of the body burdens of environmental chemicals in the general population. In Europe, a harmonized HBM program was needed to open the possibility to compare levels across borders. To explore the prospect of a harmonized European HBM project, DEMOCOPHES (DEMOnstration of a study to COordinate and Perform Human biomonitoring on a European Scale) was completed in 17 European countries. The basic measurements performed in all implemented countries of DEMOCOPHES included cadmium, cotinine and phthalate metabolites in urine and mercury in hair. In the Danish participants, significant correlationsmore » between mothers and children for mercury in hair and cotinine in urine were found. Mercury in hair was further significantly associated with intake of fish and area of residence. Cadmium was positively associated with BMI in mothers and an association between cadmium and cotinine was also found. As expected high cotinine levels were found in smoking mothers. For both mercury and cadmium significantly higher concentrations were found in the mothers compared to their children. In Denmark, the DEMOCOPHES project was co-financed by the Danish ministries of health, environment and food safety. The co-financing ministries agreed to finance a number of supplementary measurements of substances of current toxicological, public and regulatory interest. This also included blood sampling from the participants. The collected urine and blood samples were analyzed for a range of other persistent and non-persistent environmental chemicals as well as two biomarkers of effect. The variety of supplementary measurements gives the researchers further information on the exposure status of the participants and creates a basis for valuable knowledge on the pattern of exposure to various chemicals. - Highlights: • Levels of cadmium, mercury and cotinine in the Danish subpopulation are comparable to

The aim of this study was to investigate a possible link between cellular telephone use and risks for various diseases of the central nervous system (CNS). We conducted a large nationwide cohort study of 420 095 persons whose first cellular telephone subscription was between 1982 and 1995, who were followed through 2003 for hospital contacts for a diagnosis of a CNS disorder. Standardized hospitalization ratios (SHRs) were derived by dividing the number of hospital contacts in the cohort by the number expected in the Danish population. The SHRs were increased by 10-20% for migraine and vertigo. No associations were seen for amyotrophic lateral sclerosis, multiple sclerosis or epilepsy in women. SHRs decreased by 30-40% were observed for dementia (Alzheimer disease, vascular and other dementia), Parkinson disease and epilepsy among men. In analyses restricted to subscribers of 10 years or more, the SHRs remained similarly increased for migraine and vertigo and similarly decreased for Alzheimer disease and other dementia and epilepsy (in men); the other SHRs were close to unity. In conclusion, the excesses of migraine and vertigo observed in this first study on cellular telephones and CNS disease deserve further attention. An interplay of a healthy cohort effect and reversed causation bias due to prodromal symptoms impedes detection of a possible association with dementia and Parkinson disease. Identification of the factors that result in a healthy cohort might be of interest for elucidation of the etiology of these diseases.

Patients given systemic treatment for testicular germ cell cancer (GCC) are at increased risk for a second malignant neoplasm (SMN). Previous studies on SMN and causes of death lacked information on the exact treatment applied or were based on patients receiving former treatment options. To evaluate the treatment-specific risks for SMN and death in a nationwide population-based cohort of patients with GCC treated with current standard regimens. This study examined a Danish nationwide cohort of 5190 men with GCC who entered the Danish Testicular Cancer database between January 1, 1984, and December 31, 2007. Treatment results were compared with a randomly sampled, age-stratified, population-based control group. Cases of gonadal and extragonadal primary were included in the nationwide cohort. The treatments were surveillance only; retroperitoneal radiotherapy (RT); bleomycin, etoposide, and cisplatin (BEP); or more than 1 line of treatment (MTOL). Cumulative incidence and hazard ratios (HRs) for SMN and death calculated by the Cox proportional hazards model were compared with those of age-matched controls. The study population comprised 2804 patients with seminoma and 2386 with nonseminoma. The median follow-up was 14.4 years (interquartile range, 8.6-20.5 years). The 20-year cumulative incidence of SMN with death as a competing risk was 7.8% (surveillance), 7.6% (BEP), 13.5% (RT), 9.2% (MTOL), and 7.0% (controls). We found no increased risk for SMN after surveillance, while the HRs were 1.7 (95% CI, 1.4-2.0), 1.8 (95% CI, 1.5-2.3), and 3.7 (95% CI, 2.5-5.5), respectively, after BEP, RT, and MTOL. Mortality owing to non-GCC causes was decreased after surveillance, but increased by 1.3 times after BEP and RT and by 2.6 times after MTOL. Excess mortality due to SMN was found after BEP (HR, 1.6; 95% CI, 1.2-2.2), RT (HR, 2.1; 95% CI, 1.5-2.9), and MTOL (HR, 5.8; 95% CI, 3.6-9.6). We found no increased risk for SMN or death among patients undergoing surveillance only

The aim of this study was to investigate social inequality in physical inactivity among adolescents from 1991 to 2014 and to describe any changes in inequality during this period. The analyses were based on data from the Danish part of the HBSC study, which consists of seven comparable cross-sectional studies of nationally representative samples of 11-15-year old adolescents. The available data consisted of weekly time (hours) spent on vigorous physical activity and parental occupation from 30,974 participants. In summary, 8.0% of the adolescents reported to be physically inactive, i.e. spend zero hours of vigorous leisure time physical activity per week. The proportion of physically inactive adolescents was 5.4% in high social class and 7.8% and 10.8%, respectively, in middle and low social class. The absolute social inequality measured as prevalence difference between low and high social class did not change systematically across the observation period from 1991 to 2014. Compared to high social class, OR (95% CI) for physical inactivity was 1.48 (1.32-1.65) in middle social class and 2.18 (1.92-2.47) in lower social class. This relative social inequality was similar in the seven data collection waves (p=0.971). Although the gap in physical inactivity between social classes does not seem to be widening in Danish adolescents, there are still considerable differences in the activity levels between high, middle and low social class adolescents. Consequently, there is a need for a targeted physical activity intervention among adolescents from low (and middle) social class.

To investigate the diagnostic activity in general practice and the cumulative incidence of colorectal cancer (CRC) in individuals invited to the Danish national screening programme for CRC. A historical population-based cohort study. The Danish CRC screening programme and general practice. The 376,198 individuals invited to the Danish CRC screening programme from 1 March to 31 December 2014. The diagnostic activity (consultations and haemoglobin measures) in general practice in the year preceding the screening invitation and the cumulated incidence of CRC in the year following the screening invitation. Screening participants had significantly higher diagnostic activity than non-participants. Individuals with a positive faecal immunochemical test (FIT) had higher diagnostic activity compared to individuals with a negative FIT, and a small increase in the months leading up to the invitation. Individuals with a screen-detected CRC had lower diagnostic activity than individuals with no CRC. In total, 308 (25.3%) of CRCs diagnosed in the invited population were diagnosed outside the screening programme. Non-participants with CRC more often had low socio-economic status, high comorbidity and stage IV CRC than participants with CRC. There was a tendency that participants and those with a positive FIT had a higher diagnostic activity the year before the screening. This was not seen for those with CRC detected through screening. CRC must still be diagnosed in general practice in the invited population and non-participants are of special interest as they have higher risk of late stage CRC. Key Points Current awareness:Individuals with colorectal cancer (CRC) in screening may be symptomatic and CRC may still occur outside screening in the invited population. Most important points:The majority of individuals with CRC in screening cannot be expected to be diagnosed on symptomatic presentation in general practice GPs have to be aware that CRC still occurs outside screening in

The composition of milk fat from dairy cows is related to both genetic and environmental factors. Here, the effect of feed and herd was examined in 3 Scandinavian breeds, namely Danish Holstein-Friesian (DH), Danish Jersey (DJ), and Swedish Red (SR). In total, milk samples from 1,298 cows kept in indoor housing systems were collected from 61 conventional dairy herds in Denmark and Sweden. The fatty acid (FA) composition of milk was determined by gas chromatography and the content of α-tocopherol by HPLC. Based on the 17 individual FA determined, distinct FA profiles were observed for all breeds using univariate and multivariate statistics. The DJ cows were characterized by higher levels of saturated short-chain FA; in contrast, DH cows had higher content of unsaturated C18 FA, whereas higher levels of primarily C14:0, C14:1, C18:1 cis-9, and C18:3n-3 were evident in SR cows. This variation in milk fat composition across breeds was further reflected in different desaturase indices, which were generally higher in SR cows. In addition, α-tocopherol differed significantly among breeds, with DJ cows having the highest content. Herd-specific feeding plans were collected, and different feed items were separated into 4 broad feed categories, including grass products, maize silage, grain, and concentrate. The pronounced differences in overall feed composition among breeds were, to a large extent, due to regional differences between countries, with SR receiving higher levels of grain and grass silage compared with the Danish breeds. Within breeds, differences in feeding regimens among herds were furthermore higher in SR. Significant correlations between feed category and individual FA were observed in all breeds. Furthermore, variance components were estimated and used to determine the proportion of phenotypic variation that could be explained by herd. The herd effect for individual FA was generally lower for DH compared with the 2 other breeds. In addition, very low herd

To evaluate the association between chocolate intake and incident clinically apparent atrial fibrillation or flutter (AF). The Danish Diet, Cancer, and Health Study is a large population-based prospective cohort study. The present study is based on 55 502 participants (26 400 men and 29 102 women) aged 50-64 years who had provided information on chocolate intake at baseline. Incident cases of AF were ascertained by linkage with nationwide registries. During a median of 13.5 years there were 3346 cases of AF. Compared with chocolate intake less than once per month, the rate of AF was lower for people consuming 1-3 servings/month (hazard ratio (HR) 0.90, 95% confidence interval (CI) 0.82 to 0.98), 1 serving/week (HR 0.83, 95% CI 0.74 to 0.92), 2-6 servings/week (HR 0.80, 95% CI 0.71 to 0.91) and ≥1 servings/day (HR 0.84, 95% CI 0.65 to 1.09; p-linear trend <0.0001), with similar results for men and women. Accumulating evidence indicates that moderate chocolate intake may be inversely associated with AF risk, although residual confounding cannot be ruled out.

A linear regression model has been developed for the prediction of indoor (222)Rn in Danish houses. The model provides proxy radon concentrations for about 21,000 houses in a Danish case-control study on the possible association between residential radon and childhood cancer (primarily leukaemia). The model was calibrated against radon measurements in 3116 houses. An independent dataset with 788 house measurements was used for model performance assessment. The model includes nine explanatory variables, of which the most important ones are house type and geology. All explanatory variables are available from central databases. The model was fitted to log-transformed radon concentrations and it has an R(2) of 40%. The uncertainty associated with individual predictions of (untransformed) radon concentrations is about a factor of 2.0 (one standard deviation). The comparison with the independent test data shows that the model makes sound predictions and that errors of radon predictions are only weakly correlated with the estimates themselves (R(2) = 10%).

Acetaminophen (paracetamol) is the most commonly used pain and fever medication during pregnancy. Previously, a positive ecological correlation between acetaminophen use and autism spectrum disorders (ASD) has been reported but evidence from larger studies based on prospective data is lacking. We followed 64,322 children and mothers enrolled in the Danish National Birth Cohort (DNBC; 1996-2002) for average 12.7 years to investigate whether acetaminophen use in pregnancy is associated with increased risk of ASD in the offspring. Information on acetaminophen use was collected prospectively from three computer-assisted telephone interviews. We used records from the Danish hospital and psychiatric registries to identify diagnoses of ASD. At the end of follow up, 1,027 (1.6%) children were diagnosed with ASD, 345 (0.5%) with infantile autism. We found that 31% of ASD (26% of infantile autism) have also been diagnosed with hyperkinetic disorders. More than 50% women reported ever using acetaminophen in pregnancy. We used Cox proportional hazards model to estimate hazard ratio (HR) and 95% confident interval (CI). Prenatal use of acetaminophen was associated with an increased risk of ASD accompanied by hyperkinetic symptoms (HR = 1.51 95% CI 1.19-1.92), but not with other ASD cases (HR = 1.06 95% CI 0.92-1.24). Longer duration of use (i.e., use for >20 weeks in gestation) increased the risk of ASD or infantile autism with hyperkinetic symptoms almost twofold. Maternal use of acetaminophen in pregnancy was associated with ASD with hyperkinetic symptoms only, suggesting acetaminophen exposure early in fetal life may specifically impact this hyperactive behavioral phenotype.

Environmental strategies at worksites may help consumers change dietary behaviour towards a more healthy diet. The present study aimed to evaluate the availability of healthy meal options at Danish worksite canteens and to identify predictors of worksite canteens providing healthy meals. A self-administered questionnaire was randomly mailed to 1967 worksite canteen managers. Besides information and characteristics about the canteen and the worksite, the canteen managers specified the menus available. Two different health groups (Healthy and Less Healthy) were defined in three different meal categories (Sandwiches, Hot meals and Salads) as well as a combined category (Combined) combining all the three meal categories. The characteristics of the worksites were compared with regard to the different health groups. Randomly selected Danish worksite canteens. 553 Danish worksite canteen managers replied, resulting in a response rate of 29 %. Only 12 % of the canteens applied to the Healthy group combining all the three meal categories. In particular, worksites with more than 75 % female employees served healthy menus on a frequent basis. The size of the worksite was positively correlated with more healthy meal options. Furthermore, the present study suggests a positive relationship between corporate financial support and the availability of healthy meal options. Among the selected variables studied, workforce gender, company size and corporate financial support were significant predictors of the availability of healthy meal options in worksite canteens. More research is needed on the role that variance in organisation environment plays for the potential of worksite intervention, to make a difference in terms of healthy eating.

Background: Early diagnosis of childhood cancer provides hope for better prognoses. Shorter diagnostic intervals (DI) in primary care require better knowledge of the association between presenting symptoms, interpretation of symptoms and the wording of the referral letter. Methods: A Danish nationwide population-based study. Data on 550 children aged <15 years with an incident cancer diagnosis (January 2007–December 2010) were collected through questionnaires to parents (response rate=69%) and general practitioners (GPs) (response rate=87%). The DI from the first presentation in general practice until diagnosis was categorised as short or long based on quartiles. Associations between variables and long DIs were assessed using logistic regression. Results: The GPs interpreted symptoms as ‘vague' in 25.4%, ‘serious' in 50.0% and ‘alarm' in 19.0% of cases. Symptom interpretation varied by cancer type (P<0.001) and was associated with the DI (P<0.001). Vomiting was associated with a shorter DI for central nervous system (CNS) tumours, and pain with a longer DI for leukaemia. Referral letter wording was associated with DI (P<0.001); the shortest DIs were observed when cancer suspicion was raised in the letter. Conclusion: The GPs play an important role in recognising early signs of childhood cancer as their symptom interpretation and referral wording have a profound impact on the diagnostic process.

Familial Danish dementia (FDD) is an autosomal dominant neurodegenerative disease clinically characterized by the presence of cataracts, hearing impairment, cerebellar ataxia and dementia. Neuropathologically, FDD is characterized by the presence of widespread cerebral amyloid angiopathy (CAA), parenchymal amyloid deposition and neurofibrillary tangles. FDD is caused by a 10-nucleotide duplication-insertion in the BRI2 gene that generates a larger-than-normal precursor protein, of which the Danish amyloid subunit (ADan) comprises the last 34 amino acids. Here, we describe a transgenic mouse model for FDD (Tg-FDD) in which the mouse Prnp (prion protein) promoter drives the expression of the Danish mutant form of human BRI2. The main neuropathological findings in Tg-FDD mice are the presence of widespread CAA and parenchymal deposition of ADan. In addition, we observe the presence of amyloid-associated gliosis, an inflammatory response and deposition of oligomeric ADan. As the animals aged, they showed abnormal grooming behavior, an arched back, and walked with a wide-based gait and shorter steps. This mouse model may give insights on the pathogenesis of FDD and will prove useful for the development of therapeutics. Moreover, the study of Tg-FDD mice may offer new insights into the role of amyloid in neurodegeneration in other disorders, including Alzheimer disease. PMID:18410407

Recent international guidelines suggest pituitary screening in patients with moderate and severe traumatic brain injury (TBI). Predominantly isolated GH deficiency (GHD) was reported in the literature, raising the question of potential methodological bias. Our objective was to assess the prevalence of GHD in patients admitted in 2008 with TBI, with concurrent assessment of methodological bias. We conducted a nationwide population-based cohort study at tertiary referral university hospitals. Participants were Danish patients with a head trauma diagnosis from the Danish Board of Health diagnostic code registry; 439 patients and 124 healthy controls underwent dynamic assessment of GH secretion 2.5 years (median) after TBI. We evaluated the prevalence of GHD given use of 1) local versus guideline cutoffs, 2) insulin tolerance test (ITT), pyridostigmine (PD)-GHRH or GHRH-arginine (arg) test, 3) single versus repeated testing, and 4) GH assessment by assays with different isoform specificities. The prevalence of GHD was lower by local than by guideline cutoffs (12% vs 19% [PD-GHRH/GHRH-arg, P<.001]; 4.5% vs 5% [ITT, P=.9]), and by ITT than by PD-GHRH/GHRH-arg (P=.006 [local cutoffs]; P<.001 [guideline cutoffs]). Only 1% of patients had GHD according to 2 tests. GH assessment by the Immulite or iSYS assay caused no significant diagnostic differences. The study confirmed a high risk of bias in the management of pituitary testing of patients with TBI and stresses the importance of a proper control group and stringent GH testing including confirmatory testing in cohorts with low a priori likelihood of GHD such as in TBI. Our results question the evidence for newly introduced recommendations for routine pituitary assessment in TBI.

Higher protein intake, and particularly higher leucine intake, is associated with attenuated loss of lean body mass (LBM) over time in older individuals. Dietary leucine is thought to be a key mediator of anabolism. This study aimed to assess this relationship over 6 years among younger and older adult Danes. Dietary leucine intake was assessed at baseline and after 6 years in men and women, aged 35-65 years, participating in the Danish cohort of the WHO-MONICA (Multinational MONItoring of trends and determinants in CArdiovascular disease) study (n 368). Changes in LBM over the 6 years were measured by bioelectrical impedance using equations developed for this Danish population. The association between leucine and LBM changes was examined using multivariate linear regression and ANCOVA analyses adjusted for potential confounders. After adjustment for baseline LBM, sex, age, energy intake and physical activity, leucine intake was associated with LBM change in those older than 65 years (n 79), with no effect seen in those younger than 65 years. Older participants in the highest quartile of leucine intake (7·1 g/d) experienced LBM maintenance, whereas lower intakes were associated with LBM loss over 6 years (for trend: β=0·434, P=0·03). Sensitivity analysis indicated no effect modification of sex or the presence of CVD. Greater leucine intake in conjunction with adequate total protein intake was associated with long-term LBM retention in a healthy older Danish population. This study corroborates findings from laboratory investigations in relation to protein and leucine intakes and LBM change. A more diverse and larger sample is needed for confirmation of these results.

The study was undertaken to identify risk and protective factors for suicidal ideation and suicide attempts among deployed Danish soldiers. Research on suicide among Danish veterans has only been conducted to a limited degree. The method applied was a questionnaire survey administered to a population of 1,264 Danish soldiers deployed from 1990 to 2009. The data were analyzed using backward logistic regression modeling in SAS 9.2. In the logistic regression analysis, the following were significant risk factors for suicidal ideation: drug abuse, a poor financial situation before deployment, a heavy workload and/or repatriation during deployment, and attending a poor athletic and recreation program after deployment. Significant protective factors against suicidal ideation were support from friends at home during deployment and appreciation by the general population after deployment. Significant risk factors for suicide attempts were an unhappy childhood and pointless tasks during deployment. No significant protective factors against suicide attempts were identified. On the basis of the results presented in this study, intervention against suicidal behavior would benefit from screening for certain childhood issues, drug abuse, and poor financial situation before deployment. During deployment, measures should be taken to minimize the amount of meaningless tasks and heavy workloads. At the same time, efficient ways of communicating with home should be ensured. After deployment, good athletic and recreation programs should be warranted for all military personnel-including repatriated soldiers. Finally, priority should be given to ensure public appreciation of what deployed soldiers accomplish. Reprint & Copyright © 2015 Association of Military Surgeons of the U.S.

Possible Causes of a Harbour Porpoise Mass Stranding in Danish Waters in 2005

An unprecedented 85 harbour porpoises stranded freshly dead along approximately 100 km of Danish coastline from 7–15 April, 2005. This total is considerably above the mean weekly stranding rate for the whole of Denmark, both for any time of year, 1.23 animals/week (ranging from 0 to 20 during 2003–2008, excluding April 2005), and specifically in April, 0.65 animals/week (0 to 4, same period). Bycatch was established as the cause of death for most of the individuals through typical indications of fisheries interactions, including net markings in the skin and around the flippers, and loss of tail flukes. Local fishermen confirmed unusually large porpoise bycatch in nets set for lumpfish (Cyclopterus lumpus) and the strandings were attributed to an early lumpfish season. However, lumpfish catches for 2005 were not unusual in terms of season onset, peak or total catch, when compared to 2003–2008. Consequently, human activity was combined with environmental factors and the variation in Danish fisheries landings (determined through a principal component analysis) in a two-part statistical model to assess the correlation of these factors with both the presence of fresh strandings and the numbers of strandings on the Danish west coast. The final statistical model (which was forward selected using Akaike information criterion; AIC) indicated that naval presence is correlated with higher rates of porpoise strandings, particularly in combination with certain fisheries, although it is not correlated with the actual presence of strandings. Military vessels from various countries were confirmed in the area from the 7th April, en route to the largest naval exercise in Danish waters to date (Loyal Mariner 2005, 11–28 April). Although sonar usage cannot be confirmed, it is likely that ships were testing various equipment prior to the main exercise. Thus naval activity cannot be ruled out as a possible contributing factor.

The global increase in childhood obesity has in some countries been followed by an increase in type 2 diabetes mellitus (T2DM); however, the prevalence of T2DM among Danish children and adolescents is currently unknown. The aims of this cross-sectional study were to determine the prevalence of T2DM in children and adolescents in Denmark together with status on treatment, metabolic control, and late diabetic complications. Individuals were identified in the Danish Registry for Diabetes in Children and Adolescents (DanDiabKids), and clinical information regarding these was obtained from the respective pediatric departments. In total, seven young individuals (three boys) with T2DM were identified, according to the American Diabetes Association (ADA)/International Society of Pediatric and Adolecent Diabetes (ISPAD) guidelines, leading to a prevalence of T2DM at 0.6/100 000 inhabitants in Denmark. Only three of the patients had hyperglycemic symptoms at diagnosis. One boy was overweight and six were obese (two boys). Currently, no patients fulfill the treatment target of glycosylated hemoglobin (HbA1c) <7.0% (53 mmol/mol) according to the guidelines for treatment of diabetes. In 2014, there is no increasing prevalence of T2DM in children and adolescents in Denmark. Nevertheless, the current treatment regimen is not satisfying, as none of the patients truly fulfill the treatment target. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Because mastitis is very frequent and unavoidable, adding recovery information into the analysis for genetic evaluation of mastitis is of great interest from economical and animal welfare point of view. Here we have performed genome-wide association studies (GWAS) to identify associated single nucleotide polymorphisms (SNPs) and investigate the genetic background not only for susceptibility to - but also for recoverability from mastitis. Somatic cell count records from 993 Danish Holstein cows genotyped for a total of 39378 autosomal SNP markers were used for the association analysis. Single SNP regression analysis was performed using the statistical software package DMU. Substitution effect of each SNP was tested with a t -test and a genome-wide significance level of P -value < 10 -4 was used to declare significant SNP-trait association. A number of significant SNP variants were identified for both traits. Many of the SNP variants associated either with susceptibility to - or recoverability from mastitis were located in or very near to genes that have been reported for their role in the immune system. Genes involved in lymphocyte developments (e.g., MAST3 and STAB2 ) and genes involved in macrophage recruitment and regulation of inflammations ( PDGFD and PTX3 ) were suggested as possible causal genes for susceptibility to - and recoverability from mastitis, respectively. However, this is the first GWAS study for recoverability from mastitis and our results need to be validated. The findings in the current study are, therefore, a starting point for further investigations in identifying causal genetic variants or chromosomal regions for both susceptibility to - and recoverability from mastitis.

The primary care out-of-hours (OOH) service is of considerable importance; it is the main provider of freely accessible medical advice outside daytime hours, and it covers 75% of the active time in the health-care system. Although the OOH handles three million contacts annually, only little is known about the reasons for encounter, the performed clinical work and the patient perspectives. During a one-year period (2010-2011), data on patient contacts were collected using pop-up questionnaires integrated into the existing IT system. The questions explored the contents and characteristics of patient contacts. A paper-based questionnaire was sent to the included patients. Of all 700 general practitioners (GP) on duty, 383 (54.7%) participated at least once, and the participating GPs were representative of all GPs. In total, 21,457 contacts were registered; and the distribution of patient, contact and GP characteristics in OOH contacts was similar to the background contacts. Telephone consultations were most often offered to children and home visits primarily to elderly patients. The patient response rate was 51.2%. Females comprised the majority of the included contacts and of the respondents in the patient survey. The method was highly feasible for generating a representative sample of contacts to OOH services. The project has formed a substantial and valid basis for further studies and future research in the OOH service.

Understanding and scaffolding Danish schoolteachers’ motivation for using classroom-based physical activity: study protocol for a mixed methods study

PubMed Central

Skovgaard, Thomas; Bredahl, Thomas

2018-01-01

Introduction The benefits of physical activity for children’s health, both mental and physical, and its positive effects on academic achievement are well established. Research also emphasises that schools could provide a natural setting for regular physical activity. There is, however, a limited amount of knowledge about teachers’ views when it comes to integrating physical activity as part of teaching. The aim of this study is to understand teachers’ motivation for integrating physical activity as part of teaching and to assess their need for guidance and support. Methods and analysis The study uses an explanatory sequential mixed-methods design. Schools from across Denmark are included in the sample. The design comprises two separated phases—a quantitative and qualitative phase. The quantitative phase is guided by the self-determination theory where teachers’ motivation will be measured using the Work Task Motivation Scale for Teachers. The theory of scaffolding guides the qualitative phase, which consists of in-depth interviews with participants selected from the quantitative phase based on levels of motivation and on demographic information. In accordance with the study aims, the analysis of data will identify teachers’ internal and external levels of motivation. The purpose of the qualitative phase is to enhance understanding of teachers’ motivation and of their need for support in the use of physical activity in teaching. Ethics and dissemination All relevant ethics approvals have been acquired. All participants in this study will provide written informed consent prior to data collection. All data emerging from the quantitative and qualitative phase will be anonymised for analysis. Ethics approval was requested from the Regional Committee on Health Research Ethics for Southern Denmark approval ID S-20162000–40 and the Danish Data Protection Agency approval ID 16/15491). The study was deemed not notifiable by both authorities. Trial

Several studies have documented an association between socioeconomic position and survival from gynaecological cancer, but the mechanisms are unclear. The aim of this study was to examine the association between level of education and survival after endometrial cancer among Danish women; and whether differences in stage at diagnosis and comorbidity contribute to the educational differences in survival. Women with endometrial cancer diagnosed between 2005 and 2009 were identified in the Danish Gynaecological Cancer Database, with information on clinical characteristics, surgery, body mass index (BMI) and smoking status. Information on highest attained education, cohabitation and comorbidity was obtained from nationwide administrative registries. Logistic regression models were used to determine the association between level of education and cancer stage and Cox proportional hazards model for analyses of overall survival. Of the 3638 patients identified during the study period, 787 had died by the end of 2011. The group of patients with short education had a higher odds ratio (OR) for advanced stage at diagnosis, but this was not statistically significant (adjusted OR 1.20; 95% CI 0.97-1.49). The age-adjusted hazard ratio (HR) for dying of patients with short education was 1.47 (CI 95% 1.17-1.80). Adjustment for cohabitation status, BMI, smoking and comorbidity did not change HRs, but further adjustment for cancer stage yielded a HR of 1.36 (1.11-1.67). Early detection in all educational groups might reduce social inequalities in survival, however, the unexplained increased risk for death after adjustment for prognostic factors, warrants increased attention to patients with short education in all age groups throughout treatment and rehabilitation.

Life scripts are culturally shared expectations about the order and timing of life events in a prototypical life course. American and Danish undergraduates produced life story events and life scripts by listing the seven most important events in their own lives and in the lives of hypothetical people living ordinary lives. They also rated their events on several scales and completed measures of depression, PTSD symptoms, and centrality of a negative event to their lives. The Danish life script replicated earlier work; the American life script showed minor differences from the Danish life script, apparently reflecting genuine differences in shared events as well as less homogeneity in the American sample. Both consisted of mostly positive events that came disproportionately from ages 15 to 30. Valence of life story events correlated with life script valence, depression, PTSD symptoms, and identity. In the Danish undergraduates, measures of life story deviation from the life script correlated with measures of depression and PTSD symptoms. PMID:19105087

Plastic litter from shotgun ammunition on Danish coastlines - Amounts and provenance.

PubMed

Kanstrup, Niels; Balsby, Thorsten J S

2018-06-01

Plastic litter in the marine environment is a major global issue. Discarded plastic shotgun ammunition shells and discharged wads are an unwelcome addition and feature among the top ten litter items found on reference beaches in Denmark. To understand this problem, its scale and origins, collections were made by volunteers along Danish coastal shorelines. In all 3669 plastic ammunition items were collected at 68 sites along 44.6 km of shoreline. The collected items were scored for characteristic variables such as gauge and length, shot type, and the legibility of text, the erosion, and the presence of metallic components. Scores for characteristics were related to the site, area, and season and possible influences discussed. The prevalence of collected plastic shotgun litter ranges from zero to 41 items per 100 m with an average of 3.7 items per 100 m. Most ammunition litter on Danish coasts originates from hunting on Danish coastal waterbodies, but a small amount may come from further afield. North Sea coasts are the most distinctive suggesting the possible contribution of long distance drift as well as the likelihood that such litter can persist in marine habitats for decades. The pathway from initial discard to eventual wash-up and collection depends on the physical properties of plastic components, marine tides and currents, coastal topography and shoreline vegetation. Judging from the disintegration of the cartridge and the wear and decomposition of components, we conclude that there is a substantial supply of polluting plastic ammunition materials that has and will accumulate. These plastic items pose a hazard to marine ecosystems and wash up on coasts for many years to come. We recommend that responsible managers, hunters and ammunition manufacturers will take action now to reduce the problem and, thereby, protect ecosystems, wildlife and the sustainability of hunting.

In this research, we study the influence of dynamic processes in the Danish Straits on the sea surface height (SSH) oscillations in the Baltic Sea. For this purpose, we use the model of marine and oceanic circulation INMOM (Institute of Numerical Mathematics Ocean Model). The simulations were carried out for the period 2009-2010, and the coastal station data were used for verification of SSH modelling quality. Comparison of the simulated data with the ones measured in the coastal points showed us that the model does not describe SSH variability in different areas of the Baltic Sea well enough, so in the following simulation series the in situ SSH data of the coastal measurements were assimilated at the open boundary in the Danish Straits. The results of the new simulation showed us that this approach significantly increases the SSH simulation quality in all areas of the sea, where the comparison was made. In particular, the correlation coefficients between the simulated and measured SSH data increased from 0.21-0.73 to 0.81-0.90. On the basis of these results, it has been suggested that the Baltic Sea SSH variability is largely determined by the influence of the dynamic processes in the Danish Straits, which can be represented as a superposition of oscillations of different space-time scales. These oscillations can either be generated in the straits themselves, or propagate from the North Sea. For verification of this hypothesis and assessment of the oscillation propagation distance in the Baltic Sea, the following experiment was performed. At the open boundary in the Danish Straits, the six harmonics were set with the following parameters: the periods are 1.5, 3.0, 6.0, 13.5, 40.5, and 121.5 days, and the amplitude for all the harmonics is 50 cm. The results showed us that the prescribed harmonic oscillations at the open boundary propagate into all areas of the sea without changing the frequency, but with decreasing amplitude. The decrease in amplitude is not

Against all odds? Understanding the emergence of accreditation of the Danish hospitals.

PubMed

Triantafillou, Peter

2014-01-01

Despite intense critique from various parts of the medical professions, Danish hospitals have been subjected to a mandatory accreditation system known as the Danish Quality Model (Den Danske Kvalitetsmodel, DDKM) since 2009. The notion of government assemblage is employed to understand how and why, in the face of these obstacles, DDKM was ultimately implemented. It is argued that DDKM is the result of the emergence of hospital quality management assemblage in 1980s and 1990s made up by new methods of categorizing disease treatments, computerization of such treatments, concerns over cost-effectiveness, complaint registration, the availability of international hospital quality assessment systems, the mobilization of organized medical interest groups, and a tradition of consultative policymaking procedures. This assemblage was crucial for identifying quality as a problem in need of administrative intervention and for shaping the political struggle over how best to assure the quality of hospital services.

Nielsen, Kent Jacob; Lander, F; Lauritsen, J M

2015-04-01

The current study examines and compares the relationship between both macroeconomic and industry-specific business cycle indicators, and work-related injuries among construction workers in Denmark using emergency department (ED) injury data and also officially reported injuries to the Danish Working Environment Authority (WEA). The correlations between ED and WEA injury data from the catchment area of Odense University Hospital during the period 1984-2010 were tested separately for variability and trend with two general macroeconomic indicators (gross domestic product and the Danish unemployment rate) and two construction industry-specific indicators (gross value added and the number of employees). The results show that injury rates increase during economic booms and decrease during recessions. However, the regression coefficients were generally weak for both the ED (range 0.14-0.20) and WEA injuries (range 0.13-0.36). Furthermore, although there is some variability in the strength of the relationship of the different business cycle indicators, the relationships are generally not stronger for the WEA injuries than for the ED injuries, except for general unemployment. Similarly, no substantial differences in strength of relation between industry-specific and macroeconomic indicators were identified. The study shows that there was no difference in the relationship between business cycle indicators, and WEA and ED injury data. This indicates that changes in reporting behaviour do not seem to play a major role in the relation between the business cycle and workplace injuries in a Danish context.

Valid assessments of physical activity (PA) and cardiorespiratory fitness (CRF) are essential in epidemiological studies to define dose-response relationship for formulating thorough recommendations of an appropriate pattern of PA to maintain good health. The aim of this study was to validate the Danish step test, the physical activity questionnaire Active-Q, and self-rated fitness against directly measured maximal oxygen uptake (VO 2 max). A population-based subsample (n=125) was included from the "Diet, Cancer and Health-Next Generations" (DCH-NG) cohort which is under establishment. Validity coefficients, which express the correlation between measured and "true" exposure, were calculated, and misclassification across categories was evaluated. The validity of the Danish step test was moderate (women: r=.66, and men: r=.56); however, men were systematically underestimated (43% misclassification). When validating the questionnaire-derived measures of PA, leisure-time physical activity was not correlated with VO 2 max. Positive correlations were found for sports overall, but these were only significant for men: total hours per week of sports (r=.26), MET-hours per week of sports (r=.28) and vigorous sports (0.28) alone were positively correlated with VO 2 max. Finally, the percentage of misclassification was low for self-rated fitness (women: 9% and men: 13%). Thus, self-rated fitness was found to be a superior method to the Danish step test, as well as being less cost prohibitive and more practical than the VO 2 max method. Finally, even if correlations were low, they support the potential for questionnaire outcomes, particularly sports, vigorous sports, and self-rated fitness to be used to estimate CRF. © 2017 John Wiley & Sons A/S.

With increased focus on dietary intake among youth and risk of diseases later in life, it is of importance, prior to assessing diet-disease relationships, to examine the validity of the dietary assessment tool. This study's objective was to evaluate the relative validity of a self-administered web-based FFQ among Danish children aged 12 to 15 years. From a nested sub-cohort within the Danish National Birth Cohort, 124 adolescents participated. Four weeks after completion of the FFQ, adolescents were invited to complete three telephone-based 24HRs; administered 4 weeks apart. Mean or median intakes of nutrients and food groups estimated from the FFQ were compared with the mean of 3x24HRs. To assess the level of ranking we calculated the proportion of correctly classified into the same quartile, and the proportion of misclassified (into the opposite quartile). Spearman's correlation coefficients and de-attenuated coefficients were calculated to assess agreement between the FFQ and 24HRs. The mean percentage of all food groups, for adolescents classified into the same and opposite quartile was 35 and 7.5%, respectively. Mean Spearman's correlation was 0.28 for food groups and 0.35 for nutrients, respectively. Adjustment for energy and within-person variation in the 24HRs had little effect on the magnitude of the correlations for food groups and nutrients. We found overestimation by the FFQ compared with the 24HRs for fish, fruits, vegetables, oils and dressing and underestimation by the FFQ for meat/poultry and sweets. Median intake of beverages, dairy, bread, cereals, the mean total energy and carbohydrate intake did not differ significantly between the two methods. The relative validity of the FFQ compared with the 3x24HRs showed that the ranking ability differed across food groups and nutrients with best ranking for estimated intake of dairy, fruits, and oils and dressing. Larger variation was observed for fish, sweets and vegetables. For nutrients, the ranking

2013-05-01

Despite a number of risk-factor studies in different countries, the epidemiology of Campylobacter colonization in broilers, particularly spatial dependencies, is still not well understood. A series of analyses (visualization and exploratory) were therefore conducted in order to obtain a better understanding of the spatial and temporal distribution of Campylobacter in the Danish broiler population. In this study, we observed a non-random temporal occurrence of Campylobacter, with high prevalence during summer and low during winter. Significant spatio-temporal clusters were identified in the same areas in the summer months from 2007 to 2009. Range of influence between broiler farms were estimated at distances of 9.6 km and 13.5 km in different years. Identification of areas and time with greater risk indicates variable presence of risk factors with space and time. Implementation of safety measures on farms within high-risk clusters during summer could have an impact in reducing prevalence.

Addenbrooke's Cognitive Examination (ACE) is a cognitive screening test developed to detect dementia. It has been validated in several countries. Validation studies have predominantly included patients with various degrees of dementia and healthy controls. The aim of this study was to evaluate the Danish version of ACE as a screening test for early dementia in an outpatient memory clinic. Further, we wanted to investigate the ability of the ACE to discriminate patients with early Alzheimer's disease (AD) from patients with depression. 78 patients with mild AD (MMSE >or=20), 30 non-demented patients diagnosed with depression (originally referred for evaluation of cognitive symptoms), and 63 healthy volunteers, all between 60 and 85 years of age, were included. All patients were given the ACE as a supplement to the standard diagnostic work-up. The cut-off points for optimal trade-off between sensitivity and specificity for ACE were 85/86 (sensitivity 0.99, specificity 0.94). When these cut-off points were applied to the group of depressive patients, the specificity dropped to 0.64, indicating a great overlap in individual test scores for demented and depressed patients. The optimal cut-off points for ACE found in this Danish study were close to what is reported in most other European studies. The great overlap in ACE scores for demented and depressed patients emphasize that test scores must be interpreted with great caution when used in diagnostic work-up.

Increasing global migration has made immigrants' health an important topic worldwide. We examined the effect of country of birth, migrant status (refugee/family-reunified) and income on coronary heart disease (CHD) incidence. This was a historical prospective register-based cohort study. The study cohort consisted of immigrants above 18 years from non-Western countries who had obtained a residence permit in Denmark as a refugee (n = 29,045) or as a family-reunified immigrant (n = 28,435) from 1 January 1993-31 December 1999 and a Danish-born reference population (n = 229,918). First-time CHD incidence was identified from 1 January 1993-31 December 2007. Incidence ratios for 11 immigrant groups were estimated using Cox regression analysis. Immigrants from Afghanistan, Iraq, Turkey, Eastern Europe and Central Asia, South Asia, the Former Yugoslavia, and the Middle East and North Africa had significantly higher incidences of CHD (hazard ratio (HR) = 1.36; 95% confidence interval (CI): 1.05-1.75 to HR = 2.86; 95% CI: 2.01-4.08) compared with Danish-born people. Immigrants from Somalia, South and Middle America, Sub-Saharan Africa and women from East Asia and the Pacific did not differ significantly from Danish-born people, whereas immigrant men from East Asia and the Pacific had a significantly lower incidence (HR = 0.32; 95% CI: 0.17-0.62). When also including migrant status, the higher incidences were reduced. Refugee men (HR = 1.35; 95% CI: 1.11-1.65) and women (HR = 1.33; 95% CI: 1.08-1.65) had a significantly higher incidence of CHD than family-reunified immigrants. When migrant status and income were included simultaneously, the incidences decreased to an insignificant level for most immigrant groups. Most non-Western immigrant groups had a higher incidence of CHD than Danish-born people. The study revealed that migrant status and income are important underlying mechanisms of the effect of country of birth on CHD. © The European

The perceived healthiness of functional foods. A conjoint study of Danish, Finnish and American consumers' perception of functional foods.

PubMed

Bech-Larsen, Tino; Grunert, Klaus G

2003-02-01

Functional foods presumably enable the consumer to lead a healthier life without changing eating habits. Whether consumers accept this proposition or not is potentially influenced by their perceptions of the healthiness of the processing methods, enrichment components, food-types, and health claims used in the production and marketing of functional foods. Because consumers may perceive functional enrichment as interfering with nature, cultural values pertaining to man's manipulation of nature may also influence consumer acceptance of functional foods. The purpose of the study described here is to clarify to which extent Danish, Finnish and American consumers' perceptions of the healthiness of functional foods are explained by the factors mentioned above. The general results indicate that values pertaining to man's manipulation of nature is only modestly related to the acceptance of functional foods, whereas the use of different health claims, processing methods, enrichments, product types, and especially the interactions between the two latter, are important determinants of consumers' perceptions of the healthiness of functional foods.

The Little Belt strait in the inner Danish waters is characterised by a high biodiversity, and continuous monitoring of flora and fauna and the water quality is undertaken by the authorities. However, the surface sedimentology and geomorphology, i.e. elements of the geodiversity, are less well-constrained. The aim of this study is to investigate the surface sediment and morphology of a large meander bend (with a channel width of 1 km) located between the two bridges crossing the strait (a channel reach of 4 km) in order to assess a potential coupling between geodiversity and biodiversity. More specifically, the objectives are 1) to identify and classify morphological units for creating a geomorphological map, 2) to quantify surface material characteristics for creating a surface material map, and 3) to develop a conceptual model of the substrate and the morphology and morphodynamics in the meander bend between the two bridges in the strait. Preliminary results reveal a diverse morphology in the meander bend; and the annual morphological changes reveal complex sediment transport patterns along and across the bend. Likewise significant sediment sorting trends exist along and across the meander bend. Hence, the preliminary results indicate a high geodiversity in the strait.

To examine the assumption that postdeployment incidence of sickness and other absence from work are higher among Gulf War Veterans compared with nonveterans. A prospective registry study including a cohort of 721 Danish Gulf War Veterans and a control cohort of 3,629 nonveterans selected from the general Danish population. Outcome measures were up to 23 years postdeployment incidence of (1) long-term sickness absence and (2) long-term all types of absence from work. Long term with regard to sickness and other absence was defined as exceeding 8 weeks. The association between outcomes and information on deployment history was studied using time-to-event analysis. The index date was the return date from the last deployment to the Gulf. The follow-up period was the time from index date until April 27, 2014. As the main finding, no difference was found between veterans and nonveterans in the incidence rate of long-term sickness absence. After an initial short period (3 months) with elevated incidence rate of long-term absence from work among veterans, there was no difference between the cohorts. Among Danish Gulf War Veterans, no postdeployment increased risk of long-term sickness absence or long-term absence from work was found as compared with nonveterans.

Implementation of Health Impact Assessment (HIA) in Danish municipalities has been analyzed using the Roger's Diffusion of Innovation Theory. Municipalities were chosen from among those who presented their health policies on websites according to the status of inclusion of HIA into health policy. Qualitative interviews were conducted in 6 municipalities (3 with HIA inducted in their health policy and 3 without it) gathering information on knowledge and attitudes to HIA, barriers to its implementation, social system and communication channels used or expected to be used for implementation of HIA. No significant differences were found among analyzed municipalities by status of HIA inclusion into health policy. Among barriers; a lack of tools with general validity, a lack of intersectoral working culture, balance between centralized versus participatory way of working and organizational structure of a municipality, and a lack of capacities were enlisted as most relevant. The last one is a crucial factor of an internal social system of a municipality. With regards to communication channels, reporting and presentation skills of implementers and doers are of key importance. Systematic and sustainable capacity building is needed to achieve high level implementation of HIA in Danish municipalities. Development of validated tools, most importantly screening tools with focus on priorities of national public health policy would enhance implementation on municipal level.

Danish patients are positive towards fees for non-attendance in public hospitals. A qualitative study.

Patients' non-attendance is a significant problem in modern healthcare. Non-attendance delays treatment, reduces efficiency and increases healthcare costs. For several years, the introduction of financial incentives such as a non-attendance fee has been discussed in Denmark. Set in the context of a tax-financed, free-for-all healthcare system, the political hesitance to introduce fees relates to concerns that additional fees may be badly received by tax-paying citizens and may undermine the political priority of patient equity. The aim of this qualitative sub-study was to investigate patients' attitudes towards a fee for non-attendance. Six semi-structured focus group interviews were conducted with a total of 44 patients who had been informed about being charged a fee for non-attendance. Data were transcribed verbatim and analysed using a qualitative content analysis. Overall, patients' attitudes towards the non-attendance fee were positive. Non-attendance was viewed as evidence of disregard for the common free-for-all healthcare, and a fee was expected to motivate non-attendees to show up. However, most patients argued that certain groups (e.g. the mentally disabled) should be exempted from the fee. Furthermore, an implementation of fees should be easy to manage administratively and should not increase bureaucracy. In general, patients' attitudes towards implementing non-attendance fees are positive. Danish Regions, Ministry of Health and Central Denmark Region. not relevant.

Because mastitis is very frequent and unavoidable, adding recovery information into the analysis for genetic evaluation of mastitis is of great interest from economical and animal welfare point of view. Here we have performed genome-wide association studies (GWAS) to identify associated single nucleotide polymorphisms (SNPs) and investigate the genetic background not only for susceptibility to – but also for recoverability from mastitis. Somatic cell count records from 993 Danish Holstein cows genotyped for a total of 39378 autosomal SNP markers were used for the association analysis. Single SNP regression analysis was performed using the statistical software package DMU. Substitution effect of each SNP was tested with a t-test and a genome-wide significance level of P-value < 10-4 was used to declare significant SNP-trait association. A number of significant SNP variants were identified for both traits. Many of the SNP variants associated either with susceptibility to – or recoverability from mastitis were located in or very near to genes that have been reported for their role in the immune system. Genes involved in lymphocyte developments (e.g., MAST3 and STAB2) and genes involved in macrophage recruitment and regulation of inflammations (PDGFD and PTX3) were suggested as possible causal genes for susceptibility to – and recoverability from mastitis, respectively. However, this is the first GWAS study for recoverability from mastitis and our results need to be validated. The findings in the current study are, therefore, a starting point for further investigations in identifying causal genetic variants or chromosomal regions for both susceptibility to – and recoverability from mastitis.

Use of complementary and alternative medicine at Norwegian and Danish hospitals

PubMed Central

2011-01-01

Background Several studies have found that a high proportion of the population in western countries use complementary and alternative medicine (CAM). However, little is known about whether CAM is offered in hospitals. The aim of this study was to describe to what extent CAM is offered in Norwegian and Danish hospitals and investigate possible changes in Norway since 2001. Methods A one-page questionnaire was sent to all included hospitals in both countries. The questionnaire was sent to the person responsible for the clinical activity, typically the medical director. 99 hospitals in the authority (85%) in Norway and 126 in Denmark (97%) responded. Given contact persons were interviewed. Results CAM is presently offered in about 50% of Norwegian hospitals and one-third of Danish hospitals. In Norway CAM was offered in 50 hospitals, 40 of which involved acupuncture. 19 hospitals gave other alternative therapies like biofeedback, hypnosis, cupping, ear-acupuncture, herbal medicine, art therapy, homeopathy, reflexology, thought field therapy, gestalt therapy, aromatherapy, tai chi, acupressure, yoga, pilates and other. 9 hospitals offered more than one therapy form. In Denmark 38 hospitals offered acupuncture and one Eye Movement Desensitization and Reprocessing Light Therapy. The most commonly reported reason for offering CAM was scientific evidence in Denmark. In Norway it was the interest of a hospital employee, except for acupuncture where the introduction is more often initiated by the leadership and is more based on scientific evidence of effect. All persons (except one) responsible for the alternative treatment had a medical or allied health professional background and their education/training in CAM treatment varied substantially. Conclusions The extent of CAM being offered has increased substantially in Norway during the first decade of the 21st century. This might indicate a shift in attitude regarding CAM within the conventional health care system. PMID

In 2011, the St. Gallen Consensus Conference introduced the use of pathology to define the intrinsic breast cancer subtypes by application of immunohistochemical (IHC) surrogate markers ER, PR, HER2 and Ki67 with a specified Ki67 cutoff (>14%) for luminal B-like definition. Reports concerning impaired reproducibility of Ki67 estimation and threshold inconsistency led to the initiation of this quality assurance study (2013-2015). The aim of the study was to investigate inter-observer variation for Ki67 estimation in malignant breast tumors by two different quantification methods (assessment method and count method) including measure of agreement between methods. Fourteen experienced breast pathologists from 12 pathology departments evaluated 118 slides from a consecutive series of malignant breast tumors. The staining interpretation was performed according to both the Danish and Swedish guidelines. Reproducibility was quantified by intra-class correlation coefficient (ICC) and Lights Kappa with dichotomization of observations at the larger than (>) 20% threshold. The agreement between observations by the two quantification methods was evaluated by Bland-Altman plot. For the fourteen raters the median ranged from 20% to 40% by the assessment method and from 22.5% to 36.5% by the count method. Light's Kappa was 0.664 for observation by the assessment method and 0.649 by the count method. The ICC was 0.82 (95% CI: 0.77-0.86) by the assessment method vs. 0.84 (95% CI: 0.80-0.87) by the count method. Although the study in general showed a moderate to good inter-observer agreement according to both ICC and Lights Kappa, still major discrepancies were identified in especially the mid-range of observations. Consequently, for now Ki67 estimation is not implemented in the DBCG treatment algorithm.

Pelvic girdle pain is a frequent cause of sick leave among pregnant women in Denmark. Studies regarding prevention of pelvic girdle pain are sparse. The aim of this study was to examine the association between physical exercise and pelvic girdle pain in pregnancy. A nested case-control study within the Danish National Birth Cohort (n = 5304). This study used self-reported data on pelvic girdle pain obtained from an interview six months after childbirth. Information on physical exercise was obtained from the pregnancy interview around gestational week 16. The association was estimated using logistic regression analysis. Physical exercise in pregnancy was associated with decreased risk of overall pelvic girdle pain (OR = 0.87; 95% CI: 0.77-0.99, p = 0.028). Tests for trend indicated decreasing odds for pelvic girdle pain with increasing number of hours per week spent on exercise (p < 0.001). Compared to no exercise, swimming was associated with a decreased risk of pelvic girdle pain (OR = 0.73; 95% CI: 0.58-0.91, p = 0.005). The findings suggest a possible protective effect of physical exercise on pelvic girdle pain during pregnancy. Copyright © 2015 Elsevier B.V. All rights reserved.

To investigate if job insecurity and poor labour market chances predict a decline in self-rated health in the Danish workforce. Job insecurity, labour market chances, self-rated health and numerous covariates were measured in 1809 women and 1918 men who responded to a questionnaire in 1995 and again in 2000. Multivariate logistic regression analyses were used to analyse the impact of job insecurity and labour market chances measured in 1995 on decline in health in 2000. Prospective cohort study with a representative sample of the Danish workforce using the Danish Work Environment Cohort Study (DWECS). All participants were employed at baseline. Women with job insecurity had an increased risk of a decline in health at follow-up, after adjustment for all covariates (OR = 1.78, 95% CI: 1.24 to 2.54). Effect estimates were strongest among women 50 years of age or younger with poor labour market chances (OR = 2.13, 95% CI: 1.32 to 3.45). Among men, there was no main effect for job insecurity. However, men aged 50 years or younger with poor labour market chances showed an OR of 1.64 (95% CI: 0.95 to 2.84) for a decline in health. Job insecurity is a predictor for a decline in health in employed women in Denmark. Among men, a suggestive effect of job insecurity was found in employees aged 50 years or younger with poor labour market chances.

Worldwide, approximately 35 million individuals are infected with HIV; about 25 million of these live in sub-Saharan Africa. WHO proposes using treatment as prevention (TasP) to eliminate HIV. Treatment suppresses viral load, decreasing the probability an individual transmits HIV. The elimination threshold is one new HIV infection per 1000 individuals. Here, we test the hypothesis that TasP can substantially reduce epidemics and eliminate HIV. We estimate the impact of TasP, between 1996 and 2013, on the Danish HIV epidemic in men who have sex with men (MSM), an epidemic UNAIDS has identified as a priority for elimination. We use a CD4-staged Bayesian back-calculation approach to estimate incidence, and the hidden epidemic (the number of HIV-infected undiagnosed MSM). To develop the back-calculation model, we use data from an ongoing nationwide population-based study: the Danish HIV Cohort Study. Incidence, and the hidden epidemic, decreased substantially after treatment was introduced in 1996. By 2013, incidence was close to the elimination threshold: 1·4 (median, 95% Bayesian credible interval [BCI] 0·4-2·1) new HIV infections per 1000 MSM and there were only 617 (264-858) undiagnosed MSM. Decreasing incidence and increasing treatment coverage were highly correlated; a treatment threshold effect was apparent. Our study is the first to show that TasP can substantially reduce a country's HIV epidemic, and bring it close to elimination. However, we have shown the effectiveness of TasP under optimal conditions: very high treatment coverage, and exceptionally high (98%) viral suppression rate. Unless these extremely challenging conditions can be met in sub-Saharan Africa, the WHO's global elimination strategy is unlikely to succeed. National Institute of Allergy and Infectious Diseases.

To estimate the occurrence of and risk factors associated with genital warts in Danish men We conducted a cross-sectional, questionnaire-based study among almost 23 000 men aged 18-45 years, randomly sampled from the general population of Denmark. Data was collected on self-reported clinically diagnosed genital warts, and various lifestyle habits. Ever having had clinically diagnosed genital warts was reported by 7.9% of the men. The median age at first occurrence was 22 years. Genital warts within the previous 12 months were reported by 0.92% of the men, with a peak of 1.83% among men aged 21-24 years. The likelihood of reporting genital warts was strongly correlated with the lifetime number of sex partners (OR 8.0; 95% CI 6.0 to 10.8 for ≥15 partners vs 1-2 partners). Other factors associated with an increased risk for genital warts included ever having smoked and having had other sexually transmitted infections. Almost 8% of Danish men aged 18-45 years reported having had a diagnosis of genital warts. The results provide baseline information for developing and monitoring prevention strategies against genital warts, such as vaccination against human papillomavirus types 6 and 11.

Anxiety disorders and anorexia nervosa are frequently acknowledged to be highly comorbid conditions, but still, little is known about the clinical and aetiological cohesion of specific anxiety diagnoses and anorexia nervosa. Using the comprehensive Danish population registers, we aimed to determine the risk of anorexia nervosa in patients with register-detected severe anxiety disorders. We also explored whether parental psychopathology was associated with offspring's anorexia nervosa. Anxiety disorders increased the risk of subsequent anorexia nervosa, with the highest risk observed in obsessive-compulsive disorder. Especially, male anxiety patients were at an increased risk for anorexia nervosa. Furthermore, an increased risk was observed in offspring of fathers with panic disorder. A diagnosis of an anxiety disorder, specifically obsessive-compulsive disorder, constitutes a risk factor for subsequent diagnosis of anorexia nervosa. These observations support the notion that anxiety disorders and anorexia nervosa share etiological mechanisms and/or that anxiety represents one developmental pathway to anorexia nervosa.

Type 1 Diabetes (T1D) has a negative impact on psychological and overall well-being. Screening for Health-related Quality of Life (HrQoL) and addressing HrQoL issues in the clinic leads to improved well-being and metabolic outcomes. The aim of this study was to translate the generic and diabetes-specific validated multinational DISABKIDS® questionnaires into Danish, and then determine their validity and reliability. The questionnaires were translated using a validated translation procedure and completed by 99 children and adolescents from our diabetes-department; all diagnosed with T1D and were aged between 8 and 18 years old. The Rasch and the graphical log linear Rasch model (GLLRM) were used to determine validity. Monte Carlo methods and Cronbach's α were used to confirm reliability. The data did not fit a pure Rasch model but did fit a GLLRM when item six in the independence scale is excluded. The six subscales measure different aspects of HrQoL indicating that all the subscales are necessary. The questionnaire shows local dependency between items and differential item functioning (DIF). Therefore age, gender, and glycated hemoglobin (HbA1c) levels must be taken into account when comparing HrQoL between groups. The Danish versions of the DISABKIDS® chronic-generic and diabetes-specific modules provide valid and objective measurements with adequate reliability. These Danish versions are useful tools for evaluating HrQoL in Danish patients with T1D. However, guidelines on how to manage DIF and local independence will be required, and item six should be rephrased.

Livestock drivers' knowledge about dairy cow fitness for transport - A Danish questionnaire survey.

Dairy cows are transported by road to slaughter after their productive life. Cull cows are vulnerable to transport stress, and can only be transported when fit for the intended journey. However, the decision, as to whether a cow is fit is rather subjective and relies on the farmer and the livestock driver. Using a questionnaire survey, we aimed to describe knowledge about, and experiences with, dairy cow fitness for transport among Danish livestock drivers. During nine days of data collection at the three largest Danish cattle slaughterhouses, 66 drivers (55% of the national population of cattle drivers) answered a questionnaire (response rate: 97%). They were Danish males (mean age: 49years), of which 94% stated that they knew the rules regarding fitness for transport. More than half of the respondents said that physical conditions (light, space) before loading animals allowed proper assessment of fitness for transport, and 85% answered that time constraints were not a challenge for this. Thirty-five percent reported to be in doubt regarding fitness for transport of specific cows at least frequently, and given two specific questions on legislation concerning fitness for transport, only 52% of the respondents answered both correctly. The results add new knowledge about livestock drivers' approach to animal welfare. As drivers are held partly responsible for fitness for transport of animals sent to slaughter, and descriptions of fit/unfit are rather vague, livestock drivers seem to need additional education, training, assessment tools or feedback in order to optimize the welfare of animals to be transported.

A longitudinal study was carried out to investigate whether a herd that had previously tested negative for porcine circovirus type 2 (PCV2) by polymerase chain reaction (PCR) was free of PCV2 or whether the negative profiles indicate that the level of PCV2 varies over time. In eight Danish herds that had initially tested negative for PCV2 by quantitative polymerase chain reaction (PCR), additional sampling was performed. Only one of the herds was still PCV2-negative in the additional sampling and was included in the study. The herd was a finishing herd, subclinically infected with PCV2, but vaccinated against PCV2 to improve performance. The herd was monitored by taking blood samples every seventh week over a period of two years and was not found to be continuously negative for PCV2 by PCR. The first time PCV2 was detected by PCR, in May 2010, PCV2 vaccination had been withdrawn from the herd, and at the same time the herd was infected with porcine reproductive and respiratory syndrome virus (PRRS). The PCV2-negative status, measured by PCR, was obtained in the first sampling after the PCV2 vaccination had been reintroduced. When PCV2 vaccination was withdrawn again in September 2011, the herd tested positive for PCV2 by PCR, and this time it continued to be PCV2-positive, even though PCV2 vaccination had been reintroduced. A Danish finishing herd that appeared to be PCV2-free from the start of a period of two years was not free of PCV2 during the entire period.

A cross-sectional national study was initiated in order to evaluate healthcare services and survivorship from the perspective of Danish adolescents and young adults (AYAs) with cancer. The purpose of the paper was to examine (Q1) to what extend Danish AYAs experienced fears and worries about dying; (Q2) with whom, if anyone, they had shared those worries; and finally, (Q3) how fears and worries influenced their daily life. The emphasis will be on Q3. A 151-item questionnaire (including two closed- and one open-ended questions about fears of death and dying) was distributed among all 15-29-year-old Danes registered with a cancer diagnosis from 2009 to 2013. A total study population of 822 persons participated. Data was analyzed using a mixed design of descriptive statistics and qualitative content analysis. Q1: Almost 80 % of AYAs with cancer expressed some worries about death; hereof, more than half of them expressed quite a bit or very much. The analysis showed significant gender differences, whereas age and duration of disease did not have any significant impact on such thoughts. Q2: One third had not talked to anybody about his or her worries. Q3: The analysis resulted in three overall categories: fear of disease and death having little or no influence (n = 100), fear influencing in various ways (n = 215), and fear of disease and death having a substantial influence (n = 75). The majority of AYAs had experienced fears and worries about dying, but one third of them had not talked to anybody about those thoughts. It is an important clinical point that young age does not preclude fears and worries about dying in AYAs with cancer.

There is a need for an improved vaccine to better control human tuberculosis (TB), as the only currently available TB vaccine, bacillus Calmette-Guerin (BCG) delivered parenterally, offers variable levels of efficacy. Therefore, recombinant strains expressing additional antigens are being developed alongside alternative routes to parenteral delivery. There is strong evidence that BCG Moreau (RdJ) is a safe and effective vaccine in humans when given by the oral route. This study compared the efficacy of a single oral dose of wild type BCG Moreau Rio de Janeiro (RdJ), or a recombinant RdJ strain expressing Ag85B-ESAT6 fusion protein, formulated with and without lipid to enhance oral delivery, with subcutaneous BCG Danish 1331 and saline control groups in a guinea pig aerosol infection model of pulmonary tuberculosis. Protection was measured as survival at 30 weeks post-challenge and reduced bacterial load and histopathology in lungs and spleen. Results showed that a single oral dose of BCG Moreau (RdJ) or recombinant BCG Moreau (RdJ)-Ag85B-ESAT6, formulated with or without lipid, gave protection equivalent to subcutaneously delivered BCG Danish in the 30 weeks post-challenge survival study. The orally delivered vaccines gave reduced pathology scores in the lungs (three of the four formulations) and spleens (all four formulations) compared to subcutaneously delivered BCG Danish. The oral wild type BCG Moreau (RdJ) in lipid and the unformulated oral wild type BCG Moreau (RdJ) vaccine also gave statistically lower bacterial loads in the lungs and spleens, respectively, compared to subcutaneously delivered BCG Danish. This study provides further evidence to show that lipid formulation does not impair vaccine efficacy and may enhance the delivery and stability of oral vaccines intended for use in countries with poor health infrastructure. Oral delivery also avoids needles (and associated cross-infection risks) and immunisation without the need for specially trained

Tooth loss is a common health concern in older adults. We aimed to estimate the relative contributions of genetic and environmental factors to the variation in the number of teeth in middle-aged and older populations using a population-based cohort of Danish twins. The study included 5,269 Danish middle-aged or older twins who provided data on the number of teeth at baseline by structured interviews. The data were analyzed using univariate liability threshold modeling, stratified by sex and age, to estimate familial risk of tooth loss as well as estimates of heritability. In the whole cohorts, 23% of participants were edentate and 53% had retained 20 or more teeth. A statistical model including additive genetic factors and environmental factors partly shared by co-twins and partly unique to each individual twin gave the best statistical fit for the number of teeth in both age categories as well as in men and women. Overall, additive genetic factors explained 36% (95% confidence interval [CI]: 23% to 49%), common environmental factors 20% (95% CI: 9% to 31%), and unique environmental factors 44% (95% CI: 40% to 48%) of the total variation of the number of teeth. This study indicates that a substantial part of the variation in tooth loss is explained by genetic as well as environmental factors shared by co-twins. Our results implied that family background importantly affects tooth loss in both the middle-aged and the older populations. Family history is thus an important factor to take into account in dental health care.

Background Recent evidence suggests that postpartum psychiatric episodes may share similar etiological mechanisms with immune-related disorders. Pre-eclampsia is one of the most prevalent immune-related disorders of pregnancy. Multiple clinical features are shared between pre-eclampsia and postpartum psychiatric disorders, most prominently a strong link to first pregnancies. Therefore, we aimed to study if pre-eclampsia is a risk factor for first-onset postpartum psychiatric episodes. Method We conducted a cohort study using the Danish population registry, with a total of 400 717 primiparous women with a singleton delivery between 1995 and 2011. First-lifetime childbirth was the main exposure variable and the outcome of interest was first-onset postpartum psychiatric episodes. The main outcome measures were monthly incidence rate ratios (IRRs), with the period 11–12 months after birth as the reference category. Adjustments were made for age, calendar period, reproductive history, and perinatal maternal health including somatic and obstetric co-morbidity. Results Primiparous women were at particularly high risk of first-onset psychiatric episodes during the first month postpartum [IRR 2.93, 95% confidence interval (CI) 2.53–3.40] and pre-eclampsia added to that risk (IRR 4.21, 95% CI 2.89–6.13). Having both pre-eclampsia and a somatic co-morbidity resulted in the highest risk of psychiatric episodes during the 3-month period after childbirth (IRR 4.81, 95% CI 2.72–8.50). Conclusions We confirmed an association between pre-eclampsia and postpartum psychiatric episodes. The possible explanations for this association, which are not mutually exclusive, include the psychological impact of a serious medical condition such as pre-eclampsia and the neurobiological impact of pre-eclampsia-related vascular pathology and inflammation.

On February 20, 1945, during the German occupation of Denmark, members of a notorious Nazi terror organization named the Petergroup murdered four young medical doctors at the city and regional hospital of Odense. On the 70th anniversary of the crime, a symposium was organized at the Odense University Hospital, and a monument revealed close to the site of the murders in commemoration of the four victims of the crime. The young physicians were not known to be connected with the Danish resistance, and they were shot without their murderers even knowing their identities in an attempt to revenge the growing resistance in Denmark's central, third largest city, and as a reprisal for several cases where the hospital had treated wounded resistance fighters, and prevented their being handed over to the German police. The article describes the terror action of February 20, 1945 and its perpetrators, as well as other Nazi attacks on members of the Danish medical profession. It lines out the strong protest voiced by the Danish central administration against the Odense hospital killings which were on the very same day seconded by further killings and a German campaign of blowing up important Odense buildings including two newspaper printing houses. Conclusively, the authors - by way of obituaries and material from relatives of the murdered - portray the four victims of the atrocity Christian Fabricius Møller, Jørgen Hvalkof, Henning Magnus Adelsteen Dalsgaard, and Henning Ørsberg.

Although congenital abnormalities in the male reproductive tract are common, their causes remain poorly understood. We studied associations between hypertensive disorders of pregnancy (pre-gestational hypertension, gestational hypertension, and preeclampsia) and the genital anomalies, cryptorchidism (undescended testes), and hypospadias (ventrally displaced urethral meatus). We established a population of 1,073,026 Danish boys born alive between 1 January 1978 and 31 December 2012. By means of Cox regression analyses, we estimated hazard ratios with 95% confidence intervals for cryptorchidism and hypospadias according to type and severity of hypertensive disorder. Further, we used restricted cubic spline analyses to investigate the association between gestational age at onset of severe and moderate preeclampsia and the two genital anomalies. We found associations between pre-gestational hypertension and cryptorchidism [HR: 1.3 (95% CI: 1.1, 1.6)] and hypospadias [HR: 1.7 (95% CI: 1.3, 2.3)], whereas gestational hypertension was only associated with cryptorchidism [HR: 1.2 (95% CI: 1.1, 1.4)]. Boys of mothers with preeclampsia had the highest occurrence of cryptorchidism and hypospadias, increasing with preeclampsia severity. Women with HELLP syndrome faced the highest risk of having a child with both cryptorchidism [HR: 2.1 (95% CI: 1.4, 3.2)] and hypospadias [HR: 3.9 (95% CI: 2.5, 6.1)]. Further, the occurrence increased with early onset of preeclampsia diagnosis. These findings support the hypotheses that preeclampsia and genital anomalies share common etiologic factors and that placental dysfunction and androgen deficiency in early pregnancy are important in the etiology of male genital anomalies.

There is growing evidence from observational studies and randomized trials in low-income countries that vaccinations have non-specific effects. Administration of live vaccines reduces overall child morbidity and mortality, presumably due to protection against non-targeted infections. In Denmark, the live vaccine against smallpox was phased out in the 1970s due to the eradication of smallpox. We used the phasing-out period to investigate the effect of smallpox vaccination on the risk of hospitalization for infections. From the Copenhagen School Health Records Register, a cohort of 4048 individuals was sampled, of whom 3559 had information about receiving or not receiving smallpox vaccination. Infectious disease hospitalizations were identified in the Danish National Patient Register. During 87,228 person-years of follow-up, 1440 infectious disease hospitalizations occurred. Smallpox-vaccinated individuals had a reduced risk of all-cause infectious disease hospitalization compared with smallpox-unvaccinated individuals [hazard ratio (HR) 0.84; 95% confidence interval (CI) 0.72-0.98]. The reduced risk of hospitalizations was seen for most subgroups of infectious diseases. The effect may have been most pronounced after early smallpox vaccination (vaccination age <3.5 years: HR 0.81; 95% CI 0.69-0.95; vaccination age ≥ 3.5 years: HR 0.91 95% CI 0.76-1.10). Among the smallpox-vaccinated, the risk of infectious disease hospitalization increased 6% with each 1-year increase in vaccination age (HR 1.06; 95% CI 1.02-1.10). Smallpox vaccination is associated with a reduced risk of infectious disease hospitalization in a high-income setting.

This study aimed to compare family functioning and perceptions of support from nurses among Danish and Australian adult oncology patients and family members. Family can have a strong influence on the health of individuals, providing support during a health crisis such as cancer. However, family functioning and supportive care from nurses may vary across cultures and settings. A descriptive, cross-sectional comparative design with patients and family members from Denmark and Australia. Participants were asked to fill in translated versions of the Iceland-Expressive Family Functioning Questionnaire (ICE-EFFQ) and Iceland-Expressive Family Perceived Support Questionnaire (ICE-FPSQ). In total, 232 participants were recruited. The Danish cohort consisted of 56 patients and 54 family members. The Australian cohort consisted of 83 patients and 39 family members. Mean age was 59 years. No significant differences were found between Danish and Australian families. However, compared to patients, family members reported significantly lower overall family functioning, expressive emotions and communication, as well as less emotional support from nurses. Family functioning was comparable between Denmark and Australia. Family members reported less emotional support than patients. Nurses need to consider the patient and the family as a unit with complex needs that require monitoring and attention during oncology treatment. Families supporting a member with cancer have significant and often unmet needs. Assessment, information-sharing and health education need to include the family. Supportive care information may be shared between Denmark and Australia and inspires the development of common guidelines for optimal family nursing practice. © 2017 John Wiley & Sons Ltd.

The importance of supervision and of surgeons' level of experience in relation to patient outcome have been demonstrated in both hip fracture and arthroplasty surgery. The aim of this study was to describe the surgeons' experience level and the extent of supervision for: 1) fracture-related surgery in general; 2) the three most frequent primary operations and reoperations; and 3) primary operations during and outside regular working hours. A total of 9,767 surgical procedures were identified from the Danish Fracture Database (DFDB). Procedures were grouped based on the surgeons' level of experience, extent of supervision, type (primary, planned secondary or reoperation), classification (AO Müller), and whether they were performed during or outside regular hours. Interns and junior residents combined performed 46% of all procedures. A total of 90% of surgeries by interns were performed under supervision, whereas 32% of operations by junior residents were unsupervised. Supervision was absent in 14-16% and 22-33% of the three most frequent primary procedures and reoperations when performed by interns and junior residents, respectively. The proportion of unsupervised procedures by junior residents grew from 30% during to 40% (p < 0.001) outside regular hours. Interns and junior residents together performed almost half of all fracture-related surgery. The extent of supervision was generally high; however, a third of the primary procedures performed by junior residents were unsupervised. The extent of unsupervised surgery performed by junior residents was significantly higher outside regular hours. not relevant. The Danish Fracture Database ("Dansk Frakturdatabase") was approved by the Danish Data Protection Agency ID: 01321.

Situating beyond the social: understanding the role of materiality in Danish nursing education.

PubMed

Soffer, Ann Katrine B

2016-10-01

Situated learning serves as an analytical framework for learning in a community of practice and has been widely used to understand the learning process that is entailed in becoming a nurse. Yet in this paper, the difficulties encountered with the original notion of situated learning once it is applied to contemporary Danish nursing education are introduced. One issue that has arisen is the analytical requirement for an educational program to be a homogeneous, singular, and social phenomenon thereby discounting the varied and different sites and materialities found within nursing education. By using the materiality of the hospital bed as an empirical example of the way materiality also shapes practices, an alternative understanding of situated participation can emerge. This approach allows different sites and materialities to be conceptualized as equally genuine parts of the situated leaning framework. I suggest the notion of multi-configured learning, which captures the heterogeneity and materiality encountered during ethnographic fieldwork at a Danish nursing school.

The benefits of physical activity for children's health, both mental and physical, and its positive effects on academic achievement are well established. Research also emphasises that schools could provide a natural setting for regular physical activity. There is, however, a limited amount of knowledge about teachers' views when it comes to integrating physical activity as part of teaching. The aim of this study is to understand teachers' motivation for integrating physical activity as part of teaching and to assess their need for guidance and support. The study uses an explanatory sequential mixed-methods design. Schools from across Denmark are included in the sample. The design comprises two separated phases-a quantitative and qualitative phase. The quantitative phase is guided by the self-determination theory where teachers' motivation will be measured using the Work Task Motivation Scale for Teachers. The theory of scaffolding guides the qualitative phase, which consists of in-depth interviews with participants selected from the quantitative phase based on levels of motivation and on demographic information. In accordance with the study aims, the analysis of data will identify teachers' internal and external levels of motivation. The purpose of the qualitative phase is to enhance understanding of teachers' motivation and of their need for support in the use of physical activity in teaching. All relevant ethics approvals have been acquired. All participants in this study will provide written informed consent prior to data collection. All data emerging from the quantitative and qualitative phase will be anonymised for analysis. Ethics approval was requested from the Regional Committee on Health Research Ethics for Southern Denmark approval ID S-20162000-40 and the Danish Data Protection Agency approval ID 16/15491). The study was deemed not notifiable by both authorities. NCT02894346; Pre-results. © Article author(s) (or their employer(s) unless otherwise stated

Bacillus anthracis, the causative agent of anthrax, is known as one of the most genetically monomorphic species. Canonical single-nucleotide polymorphism (SNP) typing and whole-genome sequencing were used to investigate the molecular diversity of eleven B. anthracis strains isolated from cattle in Denmark between 1935 and 1988. Danish strains were assigned into five canSNP groups or lineages, i.e. A.Br.001/002 (n = 4), A.Br.Ames (n = 2), A.Br.008/011 (n = 2), A.Br.005/006 (n = 2) and A.Br.Aust94 (n = 1). The match with the A.Br.Ames lineage is of particular interest as the occurrence of such lineage in Europe is demonstrated for the first time, filling an historical gap within the phylogeography of the lineage. Comparative genome analyses of these strains with 41 isolates from other parts of the world revealed that the two Danish A.Br.008/011 strains were related to the heroin-associated strains responsible for outbreaks of injection anthrax in drug users in Europe. Eight novel diagnostic SNPs that specifically discriminate the different sub-groups of Danish strains were identified and developed into PCR-based genotyping assays. PMID:26317972

Little is known regarding paediatric medical emergency calls to Danish Emergency Medical Dispatch Centres (EMDC). This study aimed to investigate these calls, specifically the medical issues leading to them and the pre-hospital units dispatched to the paediatric emergencies. We performed a retrospective, observational study on paediatric medical emergency calls managed by the EMDC in the Region of Southern Denmark in February 2016. We reviewed audio recordings of emergency calls and ambulance records to identify calls concerning patients ≤ 15 years. We examined EMDC dispatch records to establish how the medical issues leading to these calls were classified and which pre-hospital units were dispatched to the paediatric emergencies. We analysed the data using descriptive statistics. Of a total of 7052 emergency calls in February 2016, 485 (6.9%) concerned patients ≤ 15 years. We excluded 19 and analysed the remaining 466. The reported medical issues were commonly classified as: "seizures" (22.1%), "sick child" (18.9%) and "unclear problem" (12.9%). The overall most common pre-hospital response was immediate dispatch of an ambulance with sirens and lights with a supporting physician-manned mobile emergency care unit (56.4%). The classification of medical issues and the dispatched pre-hospital units varied with patient age. We believe our results might help focus the paediatric training received by emergency medical dispatch staff on commonly encountered medical issues, such as the symptoms and conditions pertaining to the symptom categories "seizures" and "sick child". Furthermore, the results could prove useful in hypothesis generation for future studies examining paediatric medical emergency calls. Almost 7% of all calls concerned patients ≤ 15 years. Medical issues pertaining to the symptom categories "seizures", "sick child" and "unclear problem" were common and the calls commonly resulted in urgent pre-hospital responses.

Intake of the plant-derived omega-3 (n-3) fatty acid α-linolenic acid (ALA) may reduce the risk of ischemic stroke. We have investigated the associations between dietary intake of ALA and the risk of ischemic stroke and ischemic stroke subtypes. This was a follow-up study. A total of 57,053 participants aged 50-64 y were enrolled into the Danish Diet, Cancer and Health cohort between 1993 and 1997. Intake of ALA was assessed by a validated semiquantitative food frequency questionnaire. Potential incident cases of ischemic stroke were identified in the Danish National Patient Register, validated, and classified into subtypes based on assumed etiology. Statistical analyses were performed via Cox proportional hazard regression with adjustment for established ischemic stroke risk factors. A total of 1859 ischemic stroke cases were identified during a median of 13.5 y of follow-up. In multivariable analyses using restricted cubic splines adjusting for traditional risk factors for ischemic stroke, we observed no clear associations between dietary intake of ALA and the risk of total ischemic stroke or any of its subtypes including ischemic stroke due to large artery atherosclerosis, ischemic stroke due to small-vessel occlusion, and ischemic stroke due to cardio-embolism. Dietary intake of ALA was neither consistently nor appreciably associated with the risk of ischemic stroke or ischemic stroke subtypes among middle-aged Danish men and women. This study was registered at clinicaltrials.gov as NCT03258983.

To investigate the impact of prenatal antidepressant exposure on behavioural problems in children at 7 years of age. Nationwide population-based study. Danish National Birth Cohort. A cohort of 49 178 pregnant women recruited between 1996 and 2002. Data obtained from computer-assisted telephone interviews twice during pregnancy were used to identify children born to: (i) depressed women who took antidepressants during pregnancy (n = 210); (ii) depressed women who did not take any antidepressants during pregnancy (n = 231); and (iii) healthy women who were not depressed (n = 48 737). Childhood behavioural problems at 7 years of age were examined using the validated Danish parent-report version of the Strengths and Difficulties Questionnaire (SDQ). SDQ scores. No associations were observed between prenatal antidepressant exposure and abnormal SDQ scores for overall problem behaviour (adjusted relative risk, aRR 1.00; 95% confidence interval, 95% CI 0.49-2.05), hyperactivity/inattention (aRR 0.99; 95% CI 0.56-1.75), or peer problems (aRR 1.04; 95% CI 0.57-1.91). Although prenatal antidepressant exposure appeared to be associated with abnormal SDQ scores on the subscales of emotional symptoms (aRR 1.68; 95% CI 1.18-2.38) and conduct problems (aRR 1.58; 95% CI 1.03-2.42), these associations were significantly attenuated following adjustment for antenatal mood status (aRR 1.20; 95% CI 0.85-1.70 and aRR 1.19; 95% CI 0.77 1.83, respectively). Untreated prenatal depression was associated with an increased risk of all behavioural outcomes evaluated, compared with unexposed children, with significant attenuation following adjustment for antenatal mood status. The results of this study suggest that independent of maternal illness, prenatal antidepressant exposure is not associated with an increased risk of behavioural problems in children at 7 years of age. Prenatal antidepressant exposure is not associated with an increased risk of child behavioural

Clinical and population-based studies report increased prevalence of autism spectrum disorders (ASD) in individuals with anorexia nervosa and in their relatives. No nationwide study has yet been published on co-occurrence of these disorders. To investigate comorbidity of ASD in individuals with anorexia nervosa, and aggregation of ASD and anorexia nervosa in their relatives. In Danish registers we identified all individuals born in 1981-2008, their parents, and full and half siblings, and linked them to data on hospital admissions for psychiatric disorders. Risk of comorbidity of ASD in probands with anorexia nervosa and aggregation of ASD in families of anorexia nervosa probands were increased. However, the risk of comorbid and familial ASD did not differ significantly from comorbid and familial major depression or any psychiatric disorder in anorexia nervosa probands. We confirm aggregation of ASD in probands with anorexia nervosa and in their relatives; however, the relationship between anorexia nervosa and ASD appears to be non-specific. © The Royal College of Psychiatrists 2015.

The aims of this article are to (1) determine whether and to what extent general perceived health and quality of supervision predict voluntary early retirement pension (VERP) and (2) assess whether quality of supervision modifies the association between general perceived health and VERP. Employees aged 49-64 years who participated in the Danish Work Environment Cohort Study in 2000 were selected. Their questionnaire data about health and work were linked to register data on social transfer payments, among others VERP, from 2001 to 2012 in the Danish Register for Evaluation of Marginalization ( N=1167). Cox proportional hazards analyses were performed to identify the prospective association of general perceived health and quality of supervision on VERP. Relative excess risks due to interaction (RERIs) were calculated to assess whether quality of supervision modified the association between health and VERP. Employees with poor health at baseline had an increased risk of VERP during follow-up (hazard ratio [HR]=1.23; 95% confidence interval [CI] 1.02-1.49). Quality of supervision at baseline was not associated to VERP during follow-up (HR=1.04; 95% CI 0.90-1.21). There was no statistically significant interaction of poor health and poor quality of supervision with regard to risk of VERP (RERI=-0.33; 95% CI -1.79 to 1.14). This study did not support the notion that quality of supervision buffers the association between poor health and VERP. Future research is needed to determine whether other aspects of supervision, for example supervisors' opportunities to effectuate workplace adjustments, may modify the association of poor health and VERP.

The aim of this study was to translate and culturally adapt the Short Musculoskeletal Function Assessment (SMFA) into Danish (SMFA-DK) and assess the psychometric properties. SMFA was translated and cross-culturally adapted according to a standardized procedure. Minor changes in the wording in three items were made to adapt to Danish conditions. Acute patients (n = 201) and rehabilitation patients (n = 231) with musculoskeletal problems aged 18-87 years were included. The following analysis were made to evaluate psychometric quality of SMFA-DK: Reliability with Chronbach's alpha, content validity as coding according to the International Classification of Functioning, Disability and Health (ICF), floor/ceiling effects, construct validity as factor analysis, correlations between SMFA-DK and Short Form 36 and also known group method. Responsiveness and effect size were calculated. Cronbach's alpha values were between 0.79 and 0.94. SMFA-DK captured all components of the ICF, and there were no floor/ceiling effects. Factor analysis demonstrated four subscales. SMFA-DK correlated good with the SF-36 subscales for the rehabilitation patients and lower for the newly injured patients. Effect sizes were excellent and better for SMFA-DK than for SF-36. The study indicates that SMFA-DK can be a valid and responsive measure of outcome in rehabilitation settings.

This paper examines the importance of recruitment site in relation to the recruitment of ethnic minorities into health research. It presents a synthesis of experiences drawn from six interlinked Danish studies which applied different methods and used healthcare facilities and educational settings as sites for recruitment. Inspired by interpretive reviewing, data on recruitment methods from the different studies were synthesized with a focus on the various levels of recruitment success achieved. This involved an iterative process of comparison, analysis and discussion of experiences among the researchers involved. Success in recruitment seemed to depend partly on recruitment site. Using healthcare facilities as the recruitment site and healthcare professionals as gatekeepers was less efficient than using schools and employees from educational institutions. Successful study designs also depended on the possibility of singling out specific locations with a high proportion of the relevant ethnic minority target population. The findings, though based on a small number of cases, indicate that health professionals and healthcare institutions, despite their interest in high-quality health research into all population groups, fail to facilitate research access to some of the most disadvantaged groups, who need to be included in order to understand the mechanisms behind health disparities. This happens despite the genuine wish of many healthcare professionals to help facilitate such research. In this way, the findings indirectly emphasize the specific challenge of accessing more vulnerable and sick groups in research studies.

Evidence suggests that long-term trajectories of major depressive disorder (MDD) are heterogeneous. The Danish Psychiatric Central Research Register (DPCRR) provides a rare opportunity to examine patterns and correlates of long-term trajectories in a large sample of patients with moderate to severe MDD. To characterize patterns and correlates of 10-year course trajectories of MDD in the DPCRR. A cohort containing 11 640 individuals born in Denmark in 1955 or later with their first recorded MDD diagnosis in the DPCRR between 1995 and 2002 was established. Patients were followed for 10 years from the date of their initial MDD diagnosis. Data were obtained from Danish civil and psychiatric national registers in June 2013 and were analyzed from April 4, 2014, to December 17, 2015. Correlates of trajectory class membership were sex, characteristics of the first recorded MDD episode (ie, age, severity, inpatient treatment, and record of suicide attempt or self-harm), and psychiatric diagnoses in parents (ie, depression, bipolar disorder, schizophrenia-spectrum disorders, substance abuse, and anxiety or somatoform disorders). The outcome variable was past-year contact at a psychiatric hospital with a main diagnosis of MDD during each of the 10 years following the initial MDD diagnosis. Trajectories were modeled using latent class growth analysis. The sample included 11 640 individuals (7493 [64.4%] women) aged 18 to 48 years (mean [SD], 31.4 [7.3]) at their first recorded MDD diagnosis. Four trajectory classes were identified: brief contact (77.0%) (characterized by low probability of contact after 2 years); prolonged initial contact (12.8%) (characterized by high decreasing probability of contact during the first 5 years); later reentry (7.1%) (characterized by moderate probability of contact during the second 5 years); and persistent contact (3.1%) (characterized by high or moderate probability of contact throughout).

The aim of the Danish Palliative Care Database (DPD) is to monitor, evaluate, and improve the clinical quality of specialized palliative care (SPC) (ie, the activity of hospital-based palliative care teams/departments and hospices) in Denmark. The study population is all patients in Denmark referred to and/or in contact with SPC after January 1, 2010. The main variables in DPD are data about referral for patients admitted and not admitted to SPC, type of the first SPC contact, clinical and sociodemographic factors, multidisciplinary conference, and the patient-reported European Organisation for Research and Treatment of Cancer Quality of Life Questionaire-Core-15-Palliative Care questionnaire, assessing health-related quality of life. The data support the estimation of currently five quality of care indicators, ie, the proportions of 1) referred and eligible patients who were actually admitted to SPC, 2) patients who waited <10 days before admission to SPC, 3) patients who died from cancer and who obtained contact with SPC, 4) patients who were screened with European Organisation for Research and Treatment of Cancer Quality of Life Questionaire-Core-15-Palliative Care at admission to SPC, and 5) patients who were discussed at a multidisciplinary conference. In 2014, all 43 SPC units in Denmark reported their data to DPD, and all 9,434 cancer patients (100%) referred to SPC were registered in DPD. In total, 41,104 unique cancer patients were registered in DPD during the 5 years 2010-2014. Of those registered, 96% had cancer. DPD is a national clinical quality database for SPC having clinically relevant variables and high data and patient completeness.

The aim of the study was to describe travel demographics and disease patterns of patients hospitalized with travel-related diseases, and assess risk factors to improve pre-travel information and post-travel diagnostics and treatment. The study included all patients hospitalized with travel-related diseases in 2015 at a Danish infectious diseases ward. Patient data was extracted from the in-patient hospital registry. was analyzed regarding diagnoses, destination, purpose of travel and pre-travel information. 240 patients were hospitalized with a total of 289 travel-related diseases, accounting for 16.6% (240/1450) of all admissions. Febrile illnesses were the most common (39.5%, 114/289) followed by respiratory (19.7%, 57/289) and gastrointestinal diagnoses (19.0%, 55/289). Most of the diseases were acquired in Sub-Saharan Africa (35.6%, 103/289) followed by South East Asia (27.0%, 78/289), and 60.0% (144/240) of the patients were tourists. One-third (36.3%, 81/223) of the non-migrants had received pre-travel information. The lowest rate was seen in people visiting friends and relatives (18.2%, 6/32). Travel-related diseases are common among patients admitted to this Danish infectious disease ward. Malaria is the most common disease among both travelers and immigrants. In approximately one third of all the patients in our study etiology was unknown. Copyright © 2017 Elsevier Ltd. All rights reserved.

It has recently been shown that statins increase the myocardial content of prostaglandin (PG) I2 (prostacyclin) and PGE2. A systemic increase of PG production may protect the gastric mucosa and prevent gastrointestinal (GI) bleeding. We hypothesized that statins would lower the risk of GI bleeding associated with antiplatelet therapy in patients with acute coronary syndromes (ACS). We retrospectively analyzed data on 10288 patients with ACS included in the OPUS-TIMI 16 trial and received aspirin and either the oral IIb/IIIa inhibitor orbofiban or placebo. Inhospital GI bleeding rate was significantly lower in patients who were receiving lipid-lowering drugs before admission compared with those who were not (0.2% vs 0.6%, P = .031). Throughout 10 months of follow-up, GI bleeding occurred in 1.8% of non-statin users compared with 1.0% of statin users (P = .001). Statin use was associated with less overall bleeding in both the orbofiban (1.4% vs 2.4%, P = .006) and the placebo groups (0.2% vs 0.8%, P = .047). Severe and major bleeding occurred less frequently with statin use (0.8% vs 1.5%, P = .001) in both the orbofiban (1.1% vs 2.0%, P = .006) and the placebo groups (0.1% vs 0.5%, P = .119). Logistic regression analysis showed that age > 65 years, orbofiban treatment, Killip class > 1, history of cerebrovascular disease, and calcium-channel blocker use were associated with higher risk of GI bleeding, whereas statin therapy was associated with a lower risk (odds ratio 0.68, 95% CI 0.45-1.04, P = .079). Statins may exert protective effect against GI bleeding in patients with ACS. Additional studies are warranted to explore this additional potential benefit of statins.

Stringent complete remission (sCR) of acute myeloid leukemia is defined as normal hematopoiesis after therapy. Less sCR, including non-sCR, was introduced as insufficient blood platelet, neutrophil, or erythrocyte recovery. These latter characteristics were defined retrospectively as postremission transfusion dependency and were suggested to be of prognostic value. In the present report, we evaluated the prognostic impact of achieving sCR and non-sCR in the Danish National Acute Leukaemia Registry, including 769 patients registered with classical CR (ie, <5% blasts in the postinduction bone marrow analysis). Individual patients were classified as having sCR (n = 360; 46.8%) or non-sCR (n = 409; 53.2%) based on data from our national laboratory and transfusion databases. Survival analysis revealed that patients achieving sCR had superior overall survival (hazard ratio [HR], 1.34; 95% confidence interval [CI], 1.10-1.64) as well as relapse-free survival (HR, 1.25; 95% CI, 1.03-1.51) compared with those with non-sCR after adjusting for covariates. Cox regression analysis regarding the impact of the stringent criteria for blood cell recovery identified these as significant and independent variables. In conclusion, this real-life register study supports the international criteria for response evaluation on prognosis and, most importantly, documents each of the 3 lineage recovery criteria as contributing independently.

To investigate if a pending application for disability pension had an influence on the applicant's purchase of medical drugs, with a particular focus on musculoskeletal disorders and the use of painkillers. We performed a registry-based follow-up study including 12,020 applicants for disability pension in a Danish county from 1995 to 2000 and linked this information to a database of drug prescriptions. Purchase of drug was calculated for the 6-month period just before the decision and for the 6-month period 2 years later. Changes in a 2-year time period were estimated by differences in purchase rates. Furthermore, the proportion of applicants with an increased purchase of drugs and the proportion of applicants who ceased buying drugs were estimated. The results were stratified by diagnosis and result of application (awarded/rejected). The analyses were furthermore restricted to musculoskeletal disorders and the use of painkillers. At baseline 81% had a purchase and after the 2-year time period 11% ceased buying prescribed drugs. Half of all applicants increased the purchase of drugs. For musculoskeletal disorders one third had an increased purchase rate of painkillers while one fourth ceased purchase of drugs with variations in different diagnostic subgroups. The major changes of drug purchase after a pending application for disability pension are probably ascribed to characteristics of the diseases underlying the disability.

Diabetes passports for patients have been used for years in hospitals in our region. Since 2004 data have been printed from the electronic database DiabetesRASK and a new edition of the passport is given to patients at each visit. One of the objectives of the passport is to serve as a pedagogic tool. However, patients' understanding and use of the passport has never been studied. Inclusion criteria for patients: type 2 diabetes, born in Turkey (T) or Pakistan (P), regular attendees at the outpatient clinics at Hvidovre Hospital or Amager Hospital and their personal diabetes data in the database DiabetesRASK. A comparable group of Danish diabetes patients was selected. All were invited to participate in a semi-structured interview. 14 T, 11 P and 10 D patients participated in the study. 53% T and 73% P had the ability to read in their own language while 15% T and 55% P were able to read in Danish. In the groups fewer than 25% had ever shown their passport to the GP. Between 0% and 36% of any of the given questions were understood or identified correctly by T patients. Similar figures for the P and D patients were 0-55% and 30-100%. It is demonstrated that the diabetes passport is not widely used by patients. Furthermore, we found poor understanding of information on the passport in general but with great individual variability. The poorest understanding was found among immigrants, which might be the result of language problems. However, Danish patients also had insufficient understanding of the information. We recommend that the diabetes passport be rewritten so that it is more easily understood by patients and that outpatient clinics also allocate more resources to the guidance of patients concerning the passport.

In a Danish population-based case-control study, we examined the association between socioeconomic status (SES) and risk of community-acquired bacteremia, as well as the contribution of chronic diseases and substance abuse to differences in bacteremia risk. Analyses were based on 4,117 patients aged 30-65 years who were hospitalized with first-time community-acquired bacteremia during 2000-2008 and 41,170 population controls matched by sex, age, and region of residence. Individual-level information on SES (education and income), chronic diseases, and substance abuse was retrieved from public and medical registries. Conditional logistic regression was used to compute odds ratios for bacteremia. Persons of low SES had a substantially higher risk of bacteremia than those of high SES (for short duration of education vs. long duration, odds ratio = 2.30 (95% confidence interval: 2.10, 2.52); for low income vs. high income, odds ratio = 2.77 (95% confidence interval: 2.54, 3.02)). A higher prevalence of chronic diseases and substance abuse in low-SES individuals versus high-SES individuals explained 43%-48% of the socioeconomic differences in bacteremia risk. In a country with a universal welfare system, differences in the burden of chronic diseases and substance abuse seem to have major importance in explaining inequalities in bacteremia risk.

Background Information is sparse regarding the association between international travel and hospitalization with non-typhoidal Salmonella bacteremia. The aim of this study was to determine the proportion, risk factors and outcomes of travel-related non-typhoidal Salmonella bacteremia. Methods We conducted a 10-year population-based cohort study of all patients hospitalized with non-typhoidal Salmonella bacteremia in three Danish counties (population 1.6 million). We used denominator data on Danish travellers to assess the risk per 100,000 travellers according to age and travel destination. We used patients contemporaneously diagnosed with travel-related Salmonella gastroenteritis as reference patients to estimate the relative risk of presenting with travel-related bacteremia as compared with gastroenteritis. To evaluate clinical outcomes, we compared patients with travel-related bacteremia and patients with domestically acquired bacteremia in terms of length of hospital stay, number of extraintestinal focal infections and mortality after 30 and 90 days. Results We identified 311 patients hospitalized with non-typhoidal Salmonella bacteremia of whom 76 (24.4%) had a history of international travel. The risk of travel-related bacteremia per traveller was highest in the age groups 15-24 years (0.8/100,000 travellers) and 65 years and above (1.2/100,000 travellers). The sex- and age-adjusted relative risk of presenting with bacteremia was associated with travel to Sub-Saharan Africa (odds ratio 18.4; 95% confidence interval [6.9-49.5]), the Middle East (10.6; [2.1-53.2]) and South East Asia (4.0; [2.2-7.5]). We found high-risk countries in the same three regions when estimating the risk per traveller according to travel destination. Patients hospitalized with travel-related bacteremia had better clinical outcomes than patients with domestically acquired bacteremia, they had a shorter length of hospital stay (8 vs. 11 days), less extraintestinal focal infections (5 vs

Objectives To investigate the relationship between different indicators of socioeconomic position and the risk of spontaneous abortion. Design Cohort study. Setting 1996–2002, Denmark. Participants All first time participants, a total of 89 829 pregnant women, enrolled in the Danish National Birth Cohort were included in the present study. Overall, 4062 pregnancies ended in spontaneous abortion. Information on education, income and labour market attachment in the year before pregnancy was drawn from national registers. Main outcome measure Spontaneous abortion, that is, fetal death within the first 22 weeks of pregnancy, was the outcome of interest. The authors estimated HRs of spontaneous abortion using Cox regression analysis with gestational age as the underlying time scale. Results Women with <10 years of education had an elevated risk of spontaneous abortion when compared with women with >12 years of education (HR 1.19 (95% CI 1.05 to 1.34)). The HR estimates for the four lowest income quintiles were all increased (HRs between 1.09 and 1.15) as compared with the upper quintile but did not differ considerably from each other. In general, no statistically significant association was found between labour market attachment and the risk of spontaneous abortion; however, the group of women on disability pension had an increased HR of spontaneous abortion when compared with women who were employed (HR 1.32 (95% CI 0.82 to 2.13)). Conclusions Educational level and income were inversely associated with the risk of spontaneous abortion. As these factors most likely are non-causally related to spontaneous abortion, the findings indicate that factors related to social position, probably of the environmental and behavioural type, may affect spontaneous abortion risk. The study highlights the need for studies addressing such exposures in order to prevent spontaneous abortions. PMID:22734118

Denmark has been recognized as officially free (OTF) from bovine tuberculosis (bTB) since 1980. In this study, we estimated the annual probability (PIntro) of introducing Mycobacterium bovis into the Danish cattle population, through (a) imports of cattle and (b) foreign personnel working in Danish cattle herds. Data from 2000 to 2013 with date, number and origin of imported live cattle were obtained from the Danish Cattle Federation. Information on immigrants working in Danish cattle herds was obtained through a questionnaire sent by email to a sample of Danish cattle farmers (N=460). Inputs obtained from data analysis, expert opinion, the questionnaire and literature were fed into three stochastic scenario tree models used to simulate the effect of import trade patterns, and contact between immigrant workers and cattle. We also investigated the opportunity of testing animals imported from OTF countries by tuberculin skin test and animals from non-OTF countries by interferon-γ test (IFN-γ), exemplified by using year 2009 where the number of imported animals was higher than usual. Results showed that PIntro is driven mainly by importation of live cattle. The combined median annual probability of introducing M. bovis into the Danish cattle population by either imported live cattle or infectious immigrant workers, ranged from 0.3% (90% prediction interval (P.I.): 0.04%:1.4%) in 2001 to 4.9% (90% P.I.: 0.6%; 19.2%) in 2009. The median of the median PIntro estimates from the 14 years was 0.7% (median of 90% P.I.: 0.08%; 3.5%). Hence, on average, at least one introduction each 143 years could be expected, if the annual number of imported animals does not change remarkably in the future. If the number of imported animals increases, compared to the years we analyzed, additional testing of imported cattle might be considered. For example, in 2009, PIntro would have been reduced from 4.9% to 0.8% (90% P.I.: 0.1%; 4.7%) if animals from OTF countries had been tested with

The European Resuscitation Council (ERC) released new guidelines on resuscitation in 2015. For the first time, the guidelines included a separate chapter on first aid for laypersons. We analysed the current major Danish national first aid books to identify potential inconsistencies between the current books and the new evidence-based first aid guidelines. We identified first aid books from all the first aid courses offered by major Danish suppliers. Based on the new ERC first aid guidelines, we developed a checklist of 26 items within 16 different categories to assess the content; this checklist was adapted following the principle of mutually exclusive and collectively exhaustive questioning. To assess the agreement between four raters, Fleiss' kappa test was used. Items that did not reach an acceptable kappa score were excluded. We evaluated 10 first aid books used for first aid courses and published between 2009 and 2015. The content of the books complied with the new in 38% of the answers. In 12 of the 26 items, there was less than 50% consistency. These items include proximal pressure points and elevation of extremities for the control of bleeding, use of cervical collars, treatment for an open chest wound, burn dressing, dental avulsion, passive leg raising, administration of bronchodilators, adrenaline, and aspirin. Danish course material showed significant inconsistencies with the new evidence-based first aid guidelines. The new knowledge from the evidence-based guidelines should be incorporated into revised and updated first aid course material.

The article series provides an account in words and pictures of the Danish pharmaceutical industry's products from the earliest times until about 1950. Part 2 deals with products from 16 minor pharmaceutical companies, founded in the last decades of the 19th century and the first decades of the 20th century. Mentioned in chronological order, according to year of foundation, the companies are: C.R. Evers & Co., Jensen & Langebek-Petersens chemisk-techniske Fabrik, Leerbeck & Holms kemiske Fabriker, A/S Skelskør Frugtplantage, Fabriken Ferrin, Chr. F. Petri, Erslevs kemiske Laboratorium, A/S Edward Jacobsen, Th. Fallesen-Schmidt, Fabriken Ferraton, Chemia, Fabriken Kemisan, Central-Laboratoriet, F.F. Gonget & Co., A/S Ejco, and M. Schultz chemiske Fabrik. None of these minor pharmaceutical companies exist today as independent firms. All of them are either closed down or merged into other firms after a number of years. The bigger pharmaceutical companies ensured their continued existence by research and development of new products. The minor companies were not innovative to the same extent, but they played a role at an early stage in the production of Danish copy medicine and in that way a role in the establishment of a Danish generic pharmaceutical industry. The earliest products included dietetic preparations as malt products and albumin maltose products, and iron preparations, often with an admixture of medicine substances. Real medicines such as sleeping, analgesic and antipyretic medicines as well as anesthetics followed later.

Background General practice plays an important role in the cancer care pathway. Patient dissatisfaction with the diagnostic process may be expressed by changing to another general practice. Aim To compare the frequency of change of practice (COP) in patients with cancer (n = 150 216) with a matched cancer-free control cohort (n = 1 502 114) and to analyse associations with cancer type and patient characteristics. Design and setting A population-based matched cohort study using historical and prospectively collected data from Danish nationwide registers. Method COP was defined as a change of practice list, unrelated to change of address or reorganisation of the practice. Data were analysed monthly in the year before and after a cancer diagnosis. Results More patients with cancer than controls changed general practice (4.1% versus 2.6%) from 7 months before and until 12 months after diagnosis. The COP rate varied by cancer type (rectal cancer served as reference). Before the diagnosis, COP was most often seen among patients with ovarian cancer (risk ratio [RR] 1.51, 95% confidence interval [CI] = 1.10 to 2.08) and multiple myeloma (RR 1.89, 95% CI = 1.34 to 2.67). After the diagnosis, COP was most frequent among patients with brain cancer (RR 1.38, 95% CI = 1.05 to 1.82) and ovarian cancer (RR 1.51, 95% CI = 1.21 to 1.88). Conclusion Patients with cancer changed general practice more frequently than the cancer-free controls. COP variations between cancer types may be attributed to lack of diagnostic timeliness due to clinical complexity of the diagnosis and the role of the GP in the diagnostic process. PMID:27215570

In anal cancer, colostomy-free survival is a measure of anal sphincter preservation after treatment with radiotherapy or chemoradiotherapy. Failure to control anal cancer and complications of treatment are alternative indications for colostomy. However, no data exist on cause-specific colostomy rates. We examined this in a cohort study. Through national registries and review of medical records, we identified patients with anal cancer diagnosed from 1995 to 2003 who had curative-intent radiotherapy or chemoradiotherapy in four Danish centers. We computed cumulative incidence of tumor-related colostomy and therapy-related colostomy, treating colostomy and death as competing events. Follow-up started at completion of radiotherapy and continued throughout 2008. We used competing risk regression to compute hazard ratios (HRs) to compare the cumulative incidence of cause-specific colostomies between age, sex, tumor size, chemotherapy, and local excision before radiotherapy. We included 235 patients with anal cancer. The 5-year cumulative incidences of tumor-related and therapy-related colostomy were 26% (95% CI, 21% to 32%) and 8% (95% CI, 5% to 12%), respectively. Tumor size greater than 6 cm versus less than 4 cm was a risk factor for tumor-related colostomy (adjusted HR, 3.8; 95% CI, 1.7 to 8.1), and local excision before radiotherapy was a risk factor for therapy-related colostomy (adjusted HR, 4.5; 95% CI, 1.5 to 13.5). After curative-intent radiotherapy or chemoradiotherapy, one third of patients had a colostomy, of which one third were related to therapy. Large tumor size was associated with a higher risk of tumor-related colostomy, whereas history of prior excision was associated with an increased incidence of therapy-related colostomy.

Some STR loci have internal sequence variations, which are not revealed by the standard STR typing methods used in forensic genetics (PCR and fragment length analysis by capillary electrophoresis (CE)). Typing of STRs with next-generation sequencing (NGS) uncovers the sequence variation in the repeat region and in the flanking regions. In this study, 363 Danish individuals were typed for 56 STRs (26 autosomal STRs, 24 Y-STRs, and 6 X-STRs) using the ForenSeq™ DNA Signature Prep Kit to establish a Danish STR sequence database. Increased allelic diversity was observed in 34 STRs by the PCR-NGS assay. The largest increases were found in DYS389II and D12S391, where the numbers of sequenced alleles were around four times larger than the numbers of alleles determined by repeat length alone. Thirteen SNPs and one InDel were identified in the flanking regions of 12 STRs. Furthermore, 36 single positions and five longer stretches in the STR flanking regions were found to have dubious genotyping quality. The combined match probability of the 26 autosomal STRs was 10,000 times larger using the PCR-NGS assay than by using PCR-CE. The typical paternity indices for trios and duos were 500 and 100 times larger, respectively, than those obtained with PCR-CE. The assay also amplified 94 SNPs selected for human identification. Eleven of these loci were not in Hardy-Weinberg equilibrium in the Danish population, most likely because the minimum threshold for allele calling (30 reads) in the ForenSeq™ Universal Analysis Software was too low and frequent allele dropouts were not detected.

To examine the hypotheses that an overall levelling off in the prevalence of overweight and obesity during the period 2000-2008 has occurred, and that increasing social inequality in overweight and obesity exists in a nationally representative sample of Danish children and adolescents. The population comprised a random sample of 1849 children aged 4-14 years who participated in the Danish National Survey of Diet and Physical Activity in 2000-2002, 2003-2004 and 2005-2008. Parental education was chosen as an indicator of children's socioeconomic status. Body mass index (BMI) was calculated from parent-reported weight and height. Subjects were classified as overweight and obese according to the International Obesity Task Force age- and gender-specific BMI cut-off values. Crude prevalence estimates and logistic regression models were used to analyse trends in overweight and obesity as the main outcome measures. An increase was found in the crude prevalence of overweight (including obesity) in boys (12.8-21.7%, p = 0.0006), but not in girls (17.6-15.9%, p = 0.56), between 2000-2002 and 2005-2008. The prevalence of overweight increased significantly in boys of parents with low educational level only. A strong inverse social gradient in overweight and obesity was documented for boys and girls during the whole survey period. The present study showed an increase in the prevalence of overweight in Danish boys, but not in girls. This increase was due to increasing social inequality in overweight among boys. Public health initiatives aimed at preventing and reducing overweight and obesity should consider gender difference and especially target boys with parents of low educational level. © 2014 the Nordic Societies of Public Health.

To determine the mortality rate in a Danish cohort of children and adolescents diagnosed with Type 1 diabetes mellitus compared with the general population. In 1987 and 1989 we included 884 children and 1020 adolescents aged 20 years and under, corresponding to 75% of all Danish children and adolescents with Type 1 diabetes, in two nationwide studies in Denmark. Those who had participated in both investigations (n = 720) were followed until 1 January 2014, using the Danish Civil Registration System on death certificates and emigration. We derived the expected number of deaths in the cohort, using population data values from Statistics Denmark to calculate the standardized mortality ratio. Survival analysis was performed using Cox proportional hazards model. During the 24 years of follow-up, 49 (6.8%) patients died, resulting in a standardized mortality ratio of 4.8 (95% confidence interval 3.5, 6.2) compared with the age-standardized general population. A 1% increase in baseline HbA 1c (1989), available in 718 of 720 patients, was associated with all-cause mortality (hazard ratio = 1.38; 95% confidence interval 1.2, 1.6; P < 0.0001). Type 1 diabetes with multiple complications was the most common reported cause of death (36.7%). We found an increased mortality rate in this cohort of children and adolescents with Type 1 diabetes compared with the general population. The only predictor for increased risk of death up to 24 years after inclusion was the HbA 1c level in 1989. This emphasizes the importance of achieving optimal metabolic control in young people with Type 1 diabetes. © 2016 Diabetes UK.

Obesity as well as job strain is increasing, and job strain might contribute to weight gain. The objective of the current study was to examine associations between longitudinal alterations in the components of job strain and subsequent weight gain. The study was designed as a prospective cohort study with three questionnaire surveys enabling measurement of job-strain alterations over 6 years and subsequent measurements of weight gain after further 10 years of follow-up. ANCOVA and trend analyses were conducted. Job demands were measured as job busyness and speed, and control as amount of influence. Employed nurses in Denmark. We included a sub-sample of 6188 female nurses from the Danish Nurse Cohort, which consisted of the nurses who participated in surveys in 1993, 1999 and 2009. A linear trend in weight gain was seen in nurses who were often busy in 1999 between those who were rarely v. sometimes v. often busy in 1993 (P=0·03), with the largest weight gain in individuals with sustained high busyness in both years. Loss of influence between 1993 and 1999 was associated with larger subsequent weight gain than sustained high influence (P=0·003) or sustained low influence (P=0·02). For speed, no associations were found. Busyness, speed and influence differed in their relationship to subsequent weight gain. A decrease in job influence and a sustained burden of busyness were most strongly related to subsequent weight gain. Focus on job strain reduction and healthy diet is essential for public health.

The available epidemiologic evidence does not support a carcinogenic effect of silicone breast implants on breast or other cancers. Data on cancer risk other than breast cancer are limited and few studies have assessed cancer risk beyond 10-15 years after breast implantation. We extended follow-up of our earlier cohort study of Danish women with cosmetic breast implants by 7 years, yielding 30 years of follow-up for women with longest implant duration. The study population consisted of women who underwent cosmetic breast implant surgery at private clinics of plastic surgery (n = 1,653) or public hospitals (n = 1,110), and a control group of women who attended private clinics for other plastic surgery (n = 1,736), between 1973-95. Cancer incidence through 2002 was ascertained using the Danish Cancer Registry. Risk evaluation was based on computation of standardized incidence ratios (SIR) and Cox proportional hazards models, adjusting for age, calendar period and reproductive history. We observed 163 cancers among women with breast implants compared to 136.7 expected based on general population rates (SIR = 1.2; 95% confidence interval [CI] = 1.0-1.4), during a mean follow-up period of 14.4 years (range = 0-30 years). Women with breast implants experienced a reduced risk of breast cancer (SIR = 0.7; 95% CI = 0.5-1.0), and an increased risk of non-melanoma skin cancer (SIR = 2.1; 95% CI = 1.5-2.7). Stratification by age at implantation, calendar year at implantation and time since implantation showed no clear trends, however, the statistical precision was limited in these analyses. When excluding non-melanoma skin cancer, the SIR for cancer overall was 1.0 (95% CI = 0.8-1.2). With respect to other site-specific cancers, no significantly increased or decreased SIR were observed. Similar results were found when directly comparing women who had implants at private clinics with women who attended private clinics for other plastic surgery, with rate ratios for cancer

To examine the development in pedometer-determined physical activity from 2007-2008 to 2011-2012 in the adult Danish population. The study population comprised two random samples of 18-75-year-old individuals who took part in cross-sectional studies in 2007-2008 (n=224) and 2011-2012 (n=1515). Pedometer data (sealed Yamax SW 200) were obtained for seven consecutive days. Data for 1624 participants (48.2% men) were included in the analysis. An overall step-defined activity level was examined based on a graduated step index (sedentary, low active, somewhat active, active, highly active). The pedometer-determined outcomes were analysed using regression models. A borderline significant decline (p=0.077) from 8788 to 8341 steps/day (-446 (95% confidence intervals -50, 943)) was found between 2007-2008 and 2011-2012. Furthermore, a 23.7% (95% confidence intervals -41.7%, -0.1%) lower overall step-defined activity level was observed in 2011-2012 compared to 2007-2008. These changes were primarily due to a reduced level of activity among women. The proportion of individuals taking ⩾10,000 steps/day decreased non-significantly from 34.8% to 29.3%, whereas the proportion taking <5000 steps/day did not differ between survey periods. This nationally representative survey suggests an overall reduction in the physical activity level among Danish adults. The reduction was due to a shift in the population distribution from higher to lower levels of activity. If this shift is true, it is worrying from a public health perspective. Our study result needs, however, to be confirmed by other population studies. © 2015 the Nordic Societies of Public Health.

On means of transport of Danish veterinarians during the last two hundred years.

2008-01-01

For almost 20 years the authors have been selecting and editing the material referring to the means of transport which Danish veterinarians used in the 18th, 19th and 20th century. The source material contains memoirs, advertisements from veterinary medical journals, obituaries and other sources, based on which a 210-page book in the Danish language has been published. The article presents an abridged version of this book. In Denmark, the first veterinarians rendered their services at the time when this profession had not yet established itself. They were relatively poor and very often they had to walk even 15 to 20 km per day in order to visit two or three farms, where their professional help was needed. In the first half of the 19th century, the economic situation of Danish veterinarians improved, so they could afford a horse of their own. From the second half of the 19th century, the gig, a light two-wheel vehicle drawn by one horse, was in use. At the end of the 19th century, bicycles and motor-bicycles were slowly gaining ground. The gig, however, continued to be the main means of transport, because it was cheap and safe. In the 20th century, the automobile era began, but World War I prevented the widespread use of cars due to the shortage of petrol, rubber parts and the like. After the war, automobiles came into common use both in medical and veterinary practice. Only in hard winters with much snow, horses and sledges were coming to the fore again. World War II once again created the shortage of petrol and rubber tyres, so horses and gas generators were in demand. After the war, various car models completely dominated the veterinary practice, cars with built-in shelves for medicines, instruments and other medical supplies in particular. The telephone was a great help and of service to veterinarians, because many of long trips to clients were not necessary any more, thanks to the simple communication over the phone. Veterinarians were often among the first

In the Western world bovine milk products are an important protein source in human diet. The major proteins in bovine milk are the four caseins (CN), αS1-, αS2-, β-, and k-CN and the two whey proteins, β-LG and α-LA. It has been shown that both the amount of specific CN and their isoforms including post-translational modifications (PTM) influence technological properties of milk. Therefore, the aim of this study was to 1) estimate genetic parameters for individual proteins in Danish Holstein (DH) (n = 371) and Danish Jersey (DJ) (n = 321) milk, and 2) detect genomic regions associated with specific milk protein and their different PTM forms using a genome-wide association study (GWAS) approach. For DH, high heritability estimates were found for protein percentage (0.47), casein percentage (0.43), k-CN (0.77), β-LG (0.58), and α-LA (0.40). For DJ, high heritability estimates were found for protein percentage (0.70), casein percentage (0.52), and α-LA (0.44). The heritability for G-k-CN, U-k-CN and GD was higher in the DH compared to the DJ, whereas the heritability for the PD of αS1-CN was lower in DH compared to DJ, whereas the PD for αS2-CN was higher in DH compared to DJ. The GWAS results for the main milk proteins were in line what has been earlier published. However, we showed that there were SNPs specifically regulating G-k-CN in DH. Some of these SNPs were assigned to casein protein kinase genes (CSNK1G3, PRKCQ). The genetic analysis of the major milk proteins and their PTM forms revealed that these were heritable in both DH and DJ. In DH, genomic regions specific for glycosylation of k-CN were detected. Furthermore, genomic regions for the major milk proteins confirmed the regions on BTA6 (casein cluster), BTA11 (PEAP), and BTA14 (DGAT1) as important regions influencing protein composition in milk. The results from this study provide confidence that it is possible to breed for specific milk protein including the different PTM forms.

Situated learning serves as an analytical framework for learning in a community of practice and has been widely used to understand the learning process that is entailed in becoming a nurse. Yet in this paper, the difficulties encountered with the original notion of situated learning once it is applied to contemporary Danish nursing education are…
